(AP Photo/Anthony Devlin, PA) Amy Winehouse spent the night behind bars after showing up 3 hours late for questioning yesterday on Tuesday's head-butting and punching assault on two men outside a London bar, the Times reports. The visibly distressed singer was arrested and held overnight because a doctor deemed her “unfit to be interviewed.” This morning she was questioned and released with a "caution." "Amy was fully co-operative with inquiries and apologized for the incident," her spokesman said. "She thanked the police for their professional handling of the matter. There will be no further action taken." Read These Next Beyonce leaves national anthem unfinished. A space capsule carrying ashes of 160 people crashed in the ocean.
