Winehouse Gets Wrist Slap for Man Slap

No charges filed against singer following detention by police for bar incident

Britain, beware: Amy Winehouse is back on the streets.

The Grammy-winning songbird was released from police custody Saturday, a day after being arrested for allegedly head-butting a man at a bar earlier in the week.

Winehouse voluntarily turned herself in Friday and was held overnight for questioning. She received a formal caution, but no charges were filed.

According to a statement from Winehouse rep Chris Goodman, the singer "admitted to a common assault by slapping a man with an open hand and accepted a caution.

"Amy was fully cooperative with inquiries and apologized for the incident. She thanks the police for their professional handling of the matter."

The assault will remain on Winehouse's permanent record and could count against her if she is ever charged for a similar offense in the future.
