Video: So This Is How Not To Steal An ATM From A Calgary Restaurant

They fled when staff approached.

One yellow strap and one SUV led two emboldened men in Calgary to try to steal an ATM from a Boston Pizza lobby.

Calgary police released surveillance footage of the attempted theft in hopes of identifying the suspects.

On Tuesday night, the men hooked up a strap to the ATM, then used a vehicle to try and drag it out of the foyer.

It didn't work. (Watch the video at the :52 second mark.)

The wannabe robbers left — possibly in a BMW X5 SUV — when approached by restaurant staff, said police in a news release Thursday.

They described the suspects as white and in their late 20s or early 30s.
