Prosecutors say rapper Gucci Mane has pleaded guilty to aggravated assault for attacking a fan at an Atlanta nightclub.

Fulton County District Attorney's spokeswoman Yvette Jones says the 34-year-old rapper, whose real name is Radric Davis, pleaded guilty Monday to hitting a man in the head with a vodka bottle March 16, 2013, in a nightclub's VIP section.

Authorities have said the man approached Davis and was looking to have his picture taken with him. Prosecutors say the fan was an Army staff sergeant in town on a brief military leave. Authorities have said the man suffered a deep cut which required 10 stitches.

Jones says Davis's three-year sentence will be served concurrently with a 39-month federal firearms sentence that he was given in late August.
