What seemed like an innocent knock on the door led to a violent assault for a Markham man who was pistol-whipped and robbed during a home invasion on Friday.

The victim told CityNews he answered the door to see four males posing as servicemen.

They stormed the house on Bur Oak Avenue near 16th Avenue and proceeded to beat the man. He was zip-tied before being struck in the head with a gun. His injuries are not considered serious.

The victim’s girlfriend was in the house at the time. The victim says the culprits kept her in a room upstairs while they ransacked the residence.

The suspects are described as:

Suspect 1: Male, black, 22-25 years old with short hair. He was wearing jeans and a black sweater.

Suspect 2: Male, white, 20-23 year old. Six foot two, with curly hair. Wearing jeans and a dark-coloured sweater.

Suspect 3: Male, brown

Suspect 4: Male, brown
