Two teen boys face numerous assault, robbery and weapons charges in connection with a string of stabbings on Monday.

Three males, one aged 14 and two aged 17, were attacked in separate incidents in Winnipeg's North End while walking in the 400 block of Boyd Avenue, the 200 block of Powers Street and near the intersection at Redwood Avenue and Andrews Street.

They were robbed, assaulted and stabbed, police said. All three were wounded in their upper bodies and transported to the hospital.

Police officers responding to the incidents were in the area of Powers Street and Alfred Avenue when they saw the suspects run away.

The officers gave chase and caught both the teens, aged 15 and 16.

They face three counts of robbery with a weapon, two counts of assault with a weapon, possession of weapon for a dangerous purpose and aggravated assault.

The 15-year-old is also facing charges of failing to comply with conditions of a previous sentence order as well as an outstanding warrant.

Both remain in custody at the Manitoba Youth Centre.
