Two women are dead and a third is in hospital after a stabbing attack in southeast Calgary.

Emergency responders were called to the 6400 block of Penbrooke Drive S.E. at about 6:30 p.m. MT on Sunday after one of the women ran out of a house screaming and covered in blood.

She later died in a neighbour's arms, according to witnesses.

Police found two more victims inside the house. One was dead, while the other was taken to hospital with non-life-threatening injuries.

Officers arrested a male suspect near the scene and took him to hospital after concluding he had ingested an unknown substance.

Police say they don't believe it was a random incident.

The city is still reeling from last month's stabbing attack in the Brentwood area that killed five people.
