Montgomery County Police spokeswoman Officer Rebecca Innocenti urged residents to lock their cars overnight in order to avoid thefts from vehicles.

Bethesda and Chevy Chase have been hard hit by thefts from vehicles over the past two years.

“The easiest way to prevent theft from vehicles is to lock your vehicle doors,” Innocenti told County Cable Montgomery’s “County Report This Week.”

Innocenti said surveillance video from an incident in Chevy Chase shows a thief opening the doors and looking for items to steal in three unlocked cars.
