Mystery witness takes the stand in US gay suicide trial They became intimate during his second visit, when MB told the court he first noticed the webcam pointing at them. "I had just glanced over my shoulder and I noticed there was a webcam that was faced toward the direction of the bed," he said. Just being in a compromising position and seeing a camera lens - it just stuck out to me. MB said that he was aware of giggling in the background, and that when he left Mr Clementi's room there was a group of four of five students hanging around the hallway of the dormitory. He told the court: "I saw like a group of people standing there and they were looking at me. It seemed like they were looking at it me and it seemed kind of unsettling. Two days later, MB returned to the dorm and the two men again had an intimate encounter. He said: "We were both laying together in his bed. I could hear people talking in the courtyard. People joking, people laughing. It seemed like the jokes were at somebody else's expense. Mr Ravi is not charged in connection with Mr Clementi's death, but is facing 15 counts of bias intimidation, invasion of privacy and interfering with an investigation. He faces up to 10 years in jail if convicted of bias - which constitutes a hate crime. He is accused of spying on Mr Clementi and MB once, and seeking to snoop on them a second time via his webcam, sending messages on social media to encourage his friends to view the couple as well. The second viewing did not take place - Mr Clementi saw the camera and unplugged it, before complaining to university officials about what had happened and requesting a room change. He jumped off the George Washington Bridge linking New Jersey and New York a few hours later. Mr Ravi's defence team claim that he was insensitive and silly rather than a bully, and that he spied on the couple because he was alarmed at the "older" MB's "shabby" appearance and was worried he would steal from the room. The trial continues.
