London, April 27 : British singer Amy Winehouse was cautioned for common assault on April 26, following her overnight stay in a cell in a central London police station.
The troubled singer received the warning after being questioned over reports that she scuffled with two men during a raucous night out.
A Scotland Yard spokesman confirmed that the 24-year-old singer has left the police station.
Winehouse received a formal police caution, which implies she was not charged but that the incident will remain on her record and could count against her if she is ever charged with a similar offence in future.
"She has left the police station. She has been cautioned for common assault," the Telegraph quoted the Scotland Yard spokesman, as saying.
In a statement, Winehouse's spokesman said: "Amy Winehouse was questioned this morning at a London police station in connection to an incident in Camden in the early hours of April 23, 2008."
"She admitted to a common assault by slapping a man with an open hand and accepted a caution. Amy was fully co-operative with inquiries and apologised for the incident.
"She thanked the police for their professional handling of the matter. There will be no further action taken. Amy is looking forward to continuing her work on new music in the studio," he added.
A man recently alleged that Winehouse hit him when he got in her way while she was playing pool at a bar in the Camden neighborhood of London on April 23.
He said she also head-butted another man who was trying to get her a cab.
