6 'puffers' stolen in Denver during start of cold snap

DENVER - Six "puffers" have been stolen in Denver in the last 24 hours or so, police said.

Puffers are vehicles left running unattended with the keys inside. Vehicles with remote starts where the keys are not left in the vehicle while it is running are not considered puffers.

"Since the start of the cold snap yesterday, DPD has responded to 6 puffer-related auto thefts," police tweeted Thursday morning.

Drivers caught leaving their vehicles running unattended can get a ticket.

The Denver Post reported that puffers accounted for 188 car thefts in Denver in 2012.
