A 19-year-old man wanted for first-degree murder in the fatal stabbing of a Mississauga, Ont., man this weekend turned himself in to police Sunday afternoon.

Peel police had issued an arrest warrant for Mohamed Nasr Sunday afternoon, warning the public that the Mississauga man should be considered armed and dangerous and not to approach him. Nasr is wanted in connection with the death of Hamza Lamadani, also 19, who died Saturday after an altercation on Webb Drive in Mississauga.

Lamadani was found without vital signs inside a home on Harrowsmith Drive — but police have not yet explained how he made it to the residence, which would have been about a five-minute drive from where the stabbing happened.

Nasr will remain in custody Sunday night, according to a media release from Peel police. He will appear in the Ontario Court of Justice in Brampton, Ont., Monday morning.

Investigators are asking any witnesses who were around Webb Drive early Saturday to come forward with any information.

Nasr is described as being of Middle Eastern descent, standing five feet, 10 inches tall, with a medium build. He was last seen wearing a dark grey hoodie.
