One of the founders of the Indian Posse street gang was stabbed to death Monday at a Saskatchewan jail, CTV News has learned.

Daniel Wolfe died as a result of a violent incident at a Prince Albert penitentiary yesterday, said sources. Two others were seriously injured.

In 2008, Wolfe was one of six men who escaped from a jail in Regina after spending four months digging through a wall. Wolfe, who was serving time for murder, was arrested in Winnipeg days after the escape.

Both RCMP and Corrections Canada are investigating Monday's fatal stabbing of Wolfe. The maximum security wing of the prison remains in lockdown.
