The Real Housewives Of Beverly Hills star then became very angry and reportedly shouted 'Don't you know who I am?' Scroll down for video . In jail: Kim Richards was arrested on Thursday morning after becoming belligerent while intoxicated at the Polo Lounge in The Beverly Hills Hotel . Kim - who has struggled with substance abuse in the past - then headed to a bathroom and refused to come out  - which was when cops were called. A source told the website: 'She eventually locked herself in a bathroom and was refusing to come out and causing a scene. Cops had to be called at that point.' According to Beverly Hills Police Department spokesman Lt. Lincoln Hoshino, Kim appeared 'belligerent with slurred speech and wreaking of a strong odor of alcohol.' Kim allegedly cursed at officers and 'passively resisted arrest,' Hoshino said. Where is went down: After drinking vodka tonics all night a bartender at The Polo Lounge refused to serve the former child star and she then became angry saying 'Don't you know who I am?' Taking a turn for the worse: After resisting arrest Kim - who apparently smelled strongly of booze - was eventually booked into a local jail where she kicked a police officer . TMZ reports the reality star had to be dragged out of the restrooms and taken to a nearby jail where she kicked a police officer. The reality star was issued a citation for trespass, resisting arrest, battery on a police officer and drunk in public and was later released on $20,000 bail at around 10:30am in the morning. She is due to appear at the Los Angeles Superior Court on May 10. Sources close to Kim's family tell People that they are heartbroken at the star's behaviour which has become more erratic in recent months. 'It will never get better. … She's been a mess, showing up late to events and social gatherings and acting bizarre or belligerent or both.' 'They of course love [Kim] and want to help, but no one can talk any sense into her because she is so out of it.' Really friends? Kim's supposed BFF Brandi Glanville took to her Twitter shortly after hearing the arrest news . Cast support: Kim's RHOBH cast mate Lisa Rinna tweeted her support despite questioning Kim's sobriety throughout the latest season . Empathy: Eileen Davidson also shared her reaction on Twitter shortly after news of Kim's arrest . The news may be unsurprising for some of her loved ones, however, as Us Weekly reported that she has been treating friends and family members terribly as a source said: 'Kim has been on the outs from her family recently. 'Things are so bad that nobody can deal with her. You can’t even talk to her for two seconds -- she turns horrible to everybody.' This type of reported behaviour is so alarming that some experts believe it would be best for Bravo to dismiss the television personality from the reality programme according to People. 'This is one of those moments when her painfully public problem can become a personally promising opportunity to turn her life around,' said William C. Moyers from the Hazelden Betty For Foundation, 'But only if she takes seriously the reality of what's happened, by stepping away from the limelight and instead putting her attention on the help she needs and deserves to get better.' 'There is nothing funny or appealing about the reality of Kim's situation,' the expert added. 'She owes it to herself to step away from the limelight to get help. Her costars and Bravo should encourage Kim to take the first step or next step to recover.' Her on-screen group: Kim's sobriety was a major plot point during the fifth season of the hit reality series (pictured at the reunion in February) All talk? In Tuesday night's finale reunion show Kim was adamant that she is not struggling with her sobriety . During an episode of RHOBH in January, Kim maintained 'I don't drink, I don't smoke, I don't do drugs … I don't have anything to hide,' after being asked outright if she was still sober. On Tuesday's finale reunion episode of RHOBH, the former actress was defiant that everyone stop discussing her sobriety - insisting that when she popped a pill at Eileen's poker party it was a one-off under extraordinary circumstances. 'I took a pill for a chronic pain that I was having. Did I take somebody else's pill? Yes. Was that right? No.' Kim explained of taking a pill from ex-husband Monty, who has been battling cancer. Kim continued: 'Let's get this straight real quick - I am not struggling with my sobriety, nor have I struggled with my sobriety,' she said. After questioning where anyone had any real concern for her, she again insisted: 'I am sober. I have been sober for three years. I don't appreciate all the conversations that have been behind my back. And I do not have to defend myself any longer.' Defiant: Kim told her co-stars 'I am sober. I have been sober for three years and I do not have to defend myself any longer.' Family tension: The reality star also came to blows with her sister Kyle (pictured in red) during the hour-long show with Bravo's Andy Cohen . Co-star Lisa Rinna shot back 'Well Kim I'm just going to say - you showed up at my house and you were higher than a kite,' which further infuriated Kim who stressed that she had been open about that one occasion.' Kim's RHOBH cast mates expressed their reaction to their friend's arrest on their Twitter pages. 'I was sad to hear about Kim’s incident and I wish her and her family the best,' Rinna tweeted. 'I feel badly for Kim Richards and her family my thoughts and prayers are with them during this difficult time,' said Eileen Davidson. And BFF Brandi Glanville wrote: 'Wanted to say thank you to @KimRichards11 for donating to our school auction in the middle of all she has going on! so proud of her. 'Real friends are their in the good times,the bad times &especially the worst times.I am blessed with real friends & am a real friend myself.' Another one under her belt: Season five came to an end with part three of the reunion show which aired on Tuesday . Kim voluntarily entered rehab for alcohol addiction in December 2011  for the third time for and has been trying to stay sober ever since. In January 2012, Kim told Bravo's Andy Cohen in her first TV interview since her rehab stay: 'I'm an alcoholic. I had so much guilt and shame for my behavior... then I drank to cover the guilt and shame to make it go away.' In a separate sit down interview, Kim said, 'I'm getting reconnected with my kids, and that's been a huge thing for me. It's not what I expected when I came home. I was like, "Hey! I'm home! Let's all get back exactly where we were!" And they were like, "Ummm, life is a little different now." So it was like a little bit of a challenge when I got home, which I didn't expect.' She has four adult children, daughters Brooke Brinson, Whitney Davis and Kimberly Jackson, plus one son, Chad Davis.
