A man is in custody and three people are dead after an apparent crossbow attack on a residential street in Scarborough on Thursday afternoon.

Paramedics confirm the deceased are two men and a woman, all adults. Another male was taken to hospital with minor injuries.

It happened at Lawndale and Argo roads near Eglinton Avenue East and Markham Road.

Homicide detectives are on scene and have launched an investigation. No further information is currently available.

It’s not the first time a crossbow has been used to end a life in Toronto.

In December 2010, Zhou Fang shot and killed his father with a crossbow in a busy east end Toronto library.

Two years later, Fang was sentenced to life in prison with no possibility of parole for 10 years.
