For the second time this week, Boston Police report arresting a teenager who robbed a Hyde Park bank, then allegedly proved unable to figure out how to flee.

Police report nabbing a 16-year old after finding him hiding in the back of a car parked illegally a couple blocks away.

Police say the kid walked into the Blue Hills Bank branch at 1065 Truman Parkway around 11:35 a.m. yesterday, gave a teller a note and then ran out the door with some fresh cash and towards Cranmore Road.

Responding officers found a car parked where it shouldn't have been at Cranmore and Halsey roads, teen trying to keep low in the back seat, along with some cash.

He was arrested on a charge of being delinquent for unarmed bank robbery, police say.

On Tuesday, police arrested another teen they say held up the Santander Bank branch on River Street. In that case, police say he walked out of the bank, slowly enough for a bank worker to point home out to officers.
