Police are probing two separate stabbings, one serious, in Toronto’s northwest end.

Around 3:30 a.m. Sunday, a man collapsed at Jane Street and Wilson Avenue after being stabbed several times. It’s not clear where the attack happened.

Paramedics took him to Sunnybrook hospital, where he remains in serious, but stable, condition.

On Saturday night, around 9:20 p.m., a woman was stabbed in the neck at 180 Chalkfarm Dr., a highrise in the same area.

She has been released from hospital.

Police arrested a man, but he was found to be innocent.

No other details about suspects was available.
