Arizona shooter Jared Lee Loughner, who killed six people in January and injured 13 others including Congresswoman Gabrielle Giffords, had been under the watch of his college authorities for disruptive behavior and he had been asked to produce a mental health clearance before he could return from a suspension, it has emerged.

The revelations came after Arizona Superior Court Judge Stephen Villareal ordered Pima Community College to publicize documents related to the shooter.

In a note to Loughner, Vice President of Student Affairs said Loughner has been placed on immediate suspension by PCC Police. This suspension based on safety concerns associated with a series of incidents including police contacts between February of 2010 and September 23rd, 2010, the memo read.

The memo also warned him that if he tried to return to college for any reason other than with permission to meet with campus administration, he would be arrested.

Loughner, 22, had posted paranoid text messages and videos on his YouTube account. His notes and posts on MySpace and YouTube were reportedly rambling in nature and mostly unintelligible. Following the shooting, FBI investigators had found an envelope in Laugher’s house bearing handwritten words: I planned ahead, My assassination and Giffords.

Loughner, now under treatment in Federal custody, has pleaded not guilty to 49 counts associated with the January 8th shootings. In May a federal judge ruled that Loughner was mentally incompetent to stand trial.

A federal appeals court ruled on Tuesday that Loughner can't be forced to take anti-psychotic medication.
