COLUMBUS: A judge has ordered a $5 million bond for a man accused of stabbing four people in an Ohio office building.

John Mallett appeared in Franklin County Municipal Court on Thursday on charges he injured four people in Columbus on March 14 before being shot by police. He had been released from the hospital and jailed Wednesday pending the arraignment on four counts of felonious assault.

He faces an April 6 hearing to determine if the case goes before a grand jury.

Investigators say the attack appeared random. They say Mallett carried three knives into the building, which houses a career college and offices for the Ohio attorney general staff.

Mallett’s father has said his son is schizophrenic and might have been under stress.
