THE SUN: AMY WINEHOUSE was arrested last night after allegedly attacking two men while out on a wild drug-fuelled bender. The junkie singer, 24, is to be quizzed by police after claims she HEADBUTTED a Good Samaritan who hailed her a cab outside a bar. Rehab star Amy, said to have PUNCHED a second victim in the face, sank to a horrific new low while high on Class A drugs. Onlookers told how the married singer also SNOGGED a mystery fella at a nightspot and shocked punters by overturning tables and drinks. She was later seen smoking drugs in the street, walked into a lamppost, and riled a cabbie by paying only HALF her promised fare home. Trouble allegedly began after Amy arrived with pals including BABYSHAMBLES star MIK WHITNALL at a pub in Camden, North London, after a boozy afternoon in her flat. An onlooker said: She was off her face, throwing drinks around and turning over tables. Amy screamed, ‘I am a legend, get these people out. I want to take drugs.’ The frail-looking star went on to snog her mystery pal before leaving at 2.45am. Another man tried to get her a cab, but she reportedly thought he was trying to molest her and allegedly butted him in the face. A source said: He said she was a snarling tigress. It’s said she caused a serious amount of damage. The alleged victim told cops yesterday. Officers began a probe and sources said Amy will be arrested. If convicted of assault, she could face up to six months’ jail and a $3,500 fine. MORE
