A Manitoba inmate is suing the federal government for allegedly failing to protect him while he was serving a sentence at Stony Mountain Institution.

In March 2011, Rene Barrios-Lopez was stabbed more than 50 times at the jail. He was rushed to hospital in critical condition.

Barrios-Lopez said three inmates attacked him, and guards didn’t intervene until several minutes had passed.

He is also suing the three inmates involved in the attack.
