Police are trying to find who has been smashing open dozens of parking meters in Bethesda and Silver Spring to steal the coins inside.
Montgomery County Police say at least 69 meters were cracked open.
Most of the thefts took place between last Sunday and Thursday during the overnight hours.
Officials haven't released details on how much money was taken.
Some meters held as little as $2.
Each meter costs about $250 to repair, so the damage could total more than $15,000.
