Thieves in Hamilton are targeting luxury brand name coats, Hamilton police say, noting an uptick in street robberies over the past few weeks.

Officers say 13 people have reported being targets for their high-end winter coats in downtown and West Hamilton, but did not specify the incidents by neighbourhoods and time frame of the robberies.

"Victims have generally been wearing Canada Goose or Moose Knuckle brands and have been swarmed by a group of youths or the perpetrator has brandished a weapon before demanding the victim's coat," read a release from Hamilton Police.

Investigators also believe the stolen jackets, which can sell retail for as much as $1,650.00 each, are being sold through social media and word-of-mouth.

"Arrests have been made in some cases but the involved accused persons are youths who cannot be named under the (Youth Criminal Justice Act)," wrote police, which did not specify how many people have been charged.

Police were unable to immediately confirm how many suspects are arrested.

Officers recommend people avoid walking alone, especially after sunset and should follow the safest routes possible with lights and people instead of opting for shortcuts and deserted areas.
