DENVER (KDVR) — Police are warning residents in Cherry Hills Village of recent attempted break-ins and car thefts.

Commander Brennen Leininger with the Cherry Hills Village Police Department said the incidents happened late Monday night into early Tuesday morning.

Four armed suspects allegedly went to several homes and tried to open doors. Police said two high-end vehicles, to which the thieves found the keys, were stolen.

The surveillance photos show the suspects carrying what looks like firearms during the crime spree.

The department said it’s working with other Denver area agencies that are investigating similar incidents involving four suspects stealing cars.
