Tuesday after 6 on Hillcrest Street in Vienna everything appeared ordinary until neighbors heard a really loud noise.
Ali Tafreesh was driving home when he saw the grey Chrysler stopped in this front yard at Hillcrest and Marshall. Then he saw police with guns everywhere.
It turns out a 17-years-old suspect took off on foot but was eventually taken into custody in a backyard in the neighborhood.
Just before the chase, however, state police spotted the vehicle on Nutley Street near I-66 and tried to make a stop, knowing the car was connected to a robbery in Roanoke earlier that day.
After the arrest, CNN affiliate WSAV reports police searched the suspects room at Intercept Youth Services in Roanoke. It's a home for troubled teens.
Authorities found a black ski mask and a gray hooded sweatshirt - items matching descriptions of suspects in recent violent armed robberies in Montgomery County and the District.
Last week, police were looking for a group of men in ski masks targeting women walking by themselves, robbing them at gun point in Silver Spring and Northwest and Northeast D.C.
Court records show the teen caught in Vienna was also connected to the crimes based on movements tracked on his ankle bracelet.
