A Wall Street banker raped an Irish student in a 'disgusting, violent attack' because he was determined to have sex on his birthday, a court heard on Wednesday. Jason Lee forced himself on the 20-year-old in a bathroom and told her to 'shut the f*** up' so her friends in the next room would not hear. The assault ended when the girl kneed him in the groin and staggered out in such a ‘hysterical’ state she was unable to talk. Lee tried to downplay the incident and said it was 'no big deal' and dismissively told the first police officer on the scene: 'We're good, you can go', the court heard. Lee walked hand in hand with his wife Alicia into New York Suffolk County Court on Wednesday . Former Goldman Sachs managing director Jason Lee, 38, faces charges of allegedly raping a 20-year-old Irish woman in the Hamptons in August 2013 . The rape allegedly happened when Lee, 38, invited the victim and her friends to party at his rented $33,000-a-month mansion in the Hamptons on Long Island, New York during the summer of 2013. On the first day of the trial, Kerriann Kelly, the Chief of the Major Crime Bureau at Suffolk District Attorney's office, said that Lee and his victim were 'from such different worlds that they might have been from different planets'. She had spent the summer in New York on a J-1 student work visa and was staying with her brother for a night out before flying home to Ireland. Lee was a high flying executive at Goldman Sachs who lives in Manhattan, but Miss Kelly said: 'What you see is not always what you get'. She told the court: 'What you see in the court room this morning is a defendant dressed in a very professional suit, his hair is nicely combed. he is copiously taking notes as I speak. 'That's not the same individual the victim encountered in the early morning of August 20 2013. Not even close. 'What she encountered was a man who wanted one thing and one thing only, and that thing was sex. He used her to get it.' Lee has pleaded not guilty to first-degree rape, sexual misconduct and third-degree assault charges. He could face 25 years in jail if convicted. On Wednesday he walked into Suffolk District Court wearing a dark suit hand in hand with his wife Alicia, who sat in the public gallery. The court was told that Lee and his friend Rene Duncan met the victim and her friends at the trendy Georgica restaurant and lounge in Wainscott on August, 19 2013. The two men were there celebrating Lee's 37th birthday and they invited the Irish group back to his mansion a short distance away. Miss Kelly said that they were having a good time partying the night away, drinking wine and eating pizza they found in the freezer. The victim and her female friend stripped down to their underwear and got in the pool but Lee got completely naked and jumped in after them. Afterwards, around 6am, the victim went into a downstairs bathroom to change, and she 'became aware that Jason Lee was trying to force his way into the bathroom by pushing open the bathroom door,' Miss Kelly said. 'The victim saw him, he was naked, and she thought: "Is this a joke?" She pushed back and said: "What do you think you're doing?"' Miss Kelly said that the victim pushed so hard she left her fingerprints on the door, but Lee was too strong and forced the door open. As he did so she went flying onto her back, hurting her hip and scratching her leg. Miss Kelly said: 'Now he had her exactly where he wanted her, on the floor, on her back and he climbed on top of her and he held her down.' The victim tried to shove him off but she was unable to. Miss Kelly said: 'She asked him to get off her. She told him: "No"'. Lee has denied first-degree rape, sexual misconduct and third-degree assault and could face 25 years in jail if convicted . 'The defendant put his hand over her mouth and held his hand down so hard that the victim tried to bite him but was unable to. 'Then he told her to shut the f*** up, shut the f*** up. 'He didn't want anyone to interrupt what he wanted to do at that time and in that place - on his birthday'. Miss Kelly described how Lee pulled up her dress, pulled down her underwear and raped her. She said: 'He had no regard for her. 'He had no condom and the 37-year-old Jason Lee you see before you here had no regard for the 20-year-old Irish girl who was just visiting (her brother). 'He took advantage of her because he wanted to have sex and because he was going to do whatever he had to do to get it'. Miss Kelly said that the attack only stopped when the victim managed to knee him in the genitals, making him 'back off in pain'. As she waked out of the bathroom the victim was 'hysterical and crying', Miss Kelly said. Miss Kelly said: 'She couldn't say what was wrong to her. Lee was a managing director for Goldman Sachs and works at the investment bank's headquarters at 200 West Street in Lower Manhattan. A representative from the company said he left the firm last year . 'Her brother was upset and said: "What's happened to my sister? What went on in that room?"' 'The victim couldn't speak she was so hysterical.' The police were called by Mr Duncan because he thought that his car had been stolen, though the court was told that he had actually loaned it to some of the victim's friends who had left earlier. During the call to the 911 dispatcher Lee allegedly said: 'It's not big deal, there is no problem here, we don't need you to come to this house'. The victim's brother however insisted they come and said: 'There's something wrong with my sister'. Lee was the the first to approach East Hampton police officer Sarah Mortensen when she arrived at the mansion and told her: 'We're good, you can go. We don't need you. We have got this under control'. However the victim's brother also approached her and said that Lee had 'done something to my sister'. The victim then got into the officer's car and recounted her ordeal, at which point she called for backup. During this time Lee disappeared and would not be found for two hours, the court was told. Whilst in hiding he called Mr Duncan numerous times, called two taxis - one of which was turned away by officer Mortensen - and tried to hail an Uber taxi multiple times. He was eventually found in a Range Rover parked in the driveway which had tinted windows 'curled up in the fetal position', Miss Kelly said. When asked by a police officer what he was doing, he said he was 'embarrassed' and 'fell asleep' That night the victim was taken to be examined by a sexual assault nurse who found she had injuries to her vagina. She also had a scratch almost the entire length of her leg, an injury that was consistent with her account of the incident. The house on Clover Leaf Lane in East Hampton, New York, where the sexual assault allegedly occurred . At that point the victim realised that she did not have her dress and could not find it. Search warrants were executed on Lee's rental home but it was nowhere to be found. The court was told that seven months later a private investigator working for Lee delivered it to prosecutors in a box - there was no explanation why or how. In his defence Lee has hired Andrew Lankler, one of the top white collar criminal defense attorneys in New York. In his opening statement Mr Lankler said that the prosecution had been 'rushed' and that there were 'critical inconsistencies in the stories provided by the victim and the witnesses'. He said that the bathroom where the alleged rape happened was 12 feet from where the victim's brother and her friend were but that they did not hear a noise. He said that the facts were 'entirely consistent with the circumstances under which consensual sex occurs' but that it could have been 'perhaps regrettable consensual sex'. Before the allegation of rape the evening had been fun for all concerned and everyone had been taking pictures together, he said. Mr Lankler said: 'This is not a case that involves an allegation of rape in some back alley between people who are completely unknown to each other'. The trial continues.
