LAVAL, Que. -- Police say they've made an arrest in a sucker-punch attack outside a Montreal-area daycare last month that was captured on surveillance video.

In the video, a man is seen running up to the 46-year-old victim and punching him from behind in the face before fleeing on foot.

The victim immediately drops to the pavement as a woman exits the daycare to yell at the suspect.

A motive for the attack remains unclear and Laval police say the victim is still in hospital after the July 9 attack.

Montreal police arrested a 26-year-old man Thursday in a vehicle they say had been reported stolen.

Police say the suspect is expected to appear in court later today.
