JENA 6 UPDATE

Mychal Bell ordered back to lockdown.

Mychal Bell, the black Louisiana teenager at the center of the racially charged "Jena 6" case on Thursday was ordered back to jail.

He will spend 18 months in a juvenile facility, after a judge ruled he had violated his probation for earlier juvenile convictions.

Bell, 17, who was freed two weeks ago after his adult criminal conviction for beating a white classmate was overturned, was sent to the Renaissance Home for Youth in Alexandria a source told CNN.

Bell had been placed on probation until he turned 18.

The judge's decision will be appealed said Carol Powell-Lexing, one of Bell's attorneys.

Bell was freed on $45,000 bail on September 27, after an appeals court threw out his conviction on battery and conspiracy charges in adult court and remanded the case to juvenile court.

But Judge J.P. Mauffrey agreed with prosecutors that Bell had violated the probation he was given for four previous juvenile offenses, including two simple battery charges, the sources said.

Rev. Al Sharpton, who took up Bell's case, said the decision was "revenge" by the judge and called on Louisiana Gov. Kathleen Blanco to intervene.
