Chief Keef Out Of Jail, But Not Out Of Trouble? Rapper's Facebook Post Grabs Cops' Attention

Though Chief Keef was released from jail Thursday after serving 60 days on a probation violation, it wasn't even a full day until the controversial teenaged Chicago rapper was already under scrutiny anew.

Keef -- a.k.a. 17-year-old Keith Cozart -- was released without any court restrictions following a brief court hearing but was already back in hot water due to a (now deleted) Facebook post that reportedly taunted a Chicago street gang over the 2011 murder of one of their members, according to the Chicago Sun-Times.

"He’s heating things up before he’s even out," a police source told the paper of the posting.

Keef had been in custody since Jan. 15, the Chicago Tribune reports, and did not make a comment upon his release Thursday.

Keef also marked his newfound freedom with the release of a new video -- titled "Now It's Over" -- that he appeared to have recorded prior to his stint in the juvenile detention center. (Watch the video below).

Late last month, New Beginnings Church Pastor Corey Brooks -- who has been in the headlines in recent days while acting as the spokesman for the family of slain Chicago 6-month-old Jonylah Watkins -- said he would baptize Keef upon his release from jail.

“He is an entertainer, that is how he sees himself," Brooks said last month of Keef. "But at the same time, he has a God-consciousness. He is not some terror who is wreaking havoc.”

Keef was sent to jail for violating the terms of his parole by participating in a video interview with music website Pitchfork Media in which he held a rifle at a New York gun range. Cozart had been serving 18 months of probation after he pointed a gun at Chicago police officer in 2011.

Police were also previously investigating whether Cozart was involved in the shooting death of rival Chicago rapper Lil JoJo and the Interscope Records-signed rapper was also named in a child support lawsuit filed last December.

Margaret Carter, Keef's grandmother, told DNAinfo Chicago Wednesday she was happy to see her grandson released from jail but described his "devil" as his many female fans that will be gunning for him.

"Oooh, those girls are the devil. Everybody needs to just leave him alone and give him a big box of rubbers," Carter told DNAinfo.
