Amy Winehouse spent last night, April 25th, in jail. The singer went to the London police department on Friday afternoon for questioning when a doctor deemed her, “in no fit state,” to be interviewed. Winehouse who was facing assault charges was kept overnight in a cell until the doctor gave the ok to question her. She was then questioned and released. Amy was not charged but, she was given a caution for common assault.

Amy Winehouse has been arrested on assault charges. British authorities have not yet confirmed that Winehouse has been arrested but, there are pictures of her entering the London police station. Winehouse assaulted two men early Wednesday morning while hanging out at bar in Camden. One man claims that Amy hit him after he got in her way and the other man says that he was head-butted by Amy when he tried to hail her cab. This isn’t her first run in with the law and I doubt it will be her last. She has been arrested for trying to interfere with her husband’s court case and on drug possession charges. Amy Winehouse has had some good fights in the past and from the look of these pictures she is capable of doing some damage. If her singing doesn’t work out for her she can always take up a career as a MMA fighter.
