On May 31, two men were transported to the hospital with significant stab wounds due to two separate incidents in a maximum-security wing.
RCMP says at 3:30 p.m. they received a report of two separate stabbing incidents at Stony Mountain Institution.
Both stabbings took place in the maximum-security wing, but on separate ranges. RCMP say that the incidents took place three hours apart from each other.
A 24-year-old man and a 45-year-old man were both transported to hospital with significant injuries.
Manitoba RCMP's Major Crime Services, Forensic Identification Services and Stonewall RCMP worked together to investigate the incidents.
They do not believe the stabbings are related.
In the stabbing of the 45-year-old male, Attempted Murder charges are being laid against four inmates.
Two inmates are being charged with Attempted Murder regarding the 24-year-old male victim.
None of the victims and suspects are involved with both stabbings.
Officials from Stony Mountain Institution and Manitoba RCMP are now currently investigating the two stabbings further.
