A 24-year-old man arrested for the alleged stabbing of a woman last Sunday is now facing first-degree murder charges.

Toronto police said they arrived at an apartment unit near Birchmount Rd. and Danforth Ave. at around 1:50 p.m. on Sept. 10 to find an injured 50-year-old woman, who told officers that a man inside the building had a knife.

The stabbing victim, 24-year-old Julia Sokolov, was found inside an apartment unit. Police said she was rushed to hospital with life-threatening injuries.

Officers arrested the 24-year-old suspect the same day. He was charged with one count each of attempted murder and assault causing bodily harm, as well as five counts of assaulting a peace officer.

But Sokolov died of her injuries in hospital nine days after the attack.

Michal Nowaczek-Said is now facing a first-degree murder charge.

He is due in court on Sept. 21.
