Englewood police say the rapper, whose real name is John Jackson, turned himself in around 8:30 p.m. Wednesday. They say the alleged incident occurred earlier that day, but they would not identify the victim or say who reported it.
Fabolous was charged with aggravated assault and making terroristic threats.
He was released Wednesday night.
The rapper lives in Englewood with his girlfriend, Emily B, a former cast member on the "Love & Hip Hop: New York" reality show.
Fabolous' agent did not respond Thursday to a message seeking comment on the charges.
