An off-leash dog has been captured by Toronto Animal Services days after it killed another dog and injured a woman in an attack that was captured on video and prompted a safety warning from police.

The attack happened near Weston Road and Lawrence Avenue West on Tuesday afternoon.

Police said a larger dog, described as a brown pit bull mix, attacked a smaller dog and its owner without provocation.

The owner sustained non-life-threatening injuries and the smaller dog died as a result.

On Wednesday afternoon, police announced the arrest of 40-year-old Mohamoud Abdiwa Ahmed, the owner of the larger dog.

Ahmed was charged with several offences, including criminal negligence causing bodily harm, obstruction of a peace officer, and obstructing, interrupting or interfering with the lawful use, enjoyment or operation of property.

He also faces additional charges under the Dog Owners’ Liability Act.

CTV News previously obtained video footage of the attack. The footage appeared to show the larger dog walking ahead of its owner without a leash before charging toward the smaller dog. The smaller dog was being walked by an owner who appeared to be pushing a stroller.

The dog was not located until Thursday evening, when it was found in the same area where the attack occurred.

Toronto Police thanked the public for their help in locating the dog.

Toronto Animal Services took custody of the dog and police said the investigation remains ongoing.
