Amy Winehouse has reportedly checked into rehab again after failing to comply with local police over an alleged assault charge. Checking in to an exclusive Harley Street clinic on Saturday, Winehouse avoided being arrested after failing to attend police questioning over allegations that she hit Sherene Flash, 30, at a party in September. “She’s doing so many drugs she is completely out of it. It’s hardly surprising she missed the interview.” a friend told The Sun. Meanwhile the police seem to be annoyed with the Grammy Award-winning star. One officer told The Sun, ” She needs to show the law some respect.” No further information was available regarding Winehouse’s assault case or rehab stay at press time.
