Boston Police report a teen was beaten and robbed in the Franklin Field housing project yesterday.

Police say an acquaintance of the teen stopped him as he walked through the project and asked him if he had $5 for food:

The victim reported that he told the friend that he had no small bills and only had $100 dollar bills, which he showed to him. The victim reported that he walked away from his "friend" and soon thereafter noticed that there was a large group of people from the nearby basketball court following him.

He was then knocked to the ground, kicked and hit in the head with a hammer, police say, adding they arrested a 16-year-old on an unarmed-robbery charge in connection with the case. The victim was taken to Carney Hospital, expected to survive.

Meanwhile, four alleged thugs (one from Erie, Pa.) learned that Green Line trolleys don't make the best getaway vehicles because if police chasing you from a robbery hear you've just gone down the outbound stairs at Copley, they're going to radio ahead and have you pulled off the train at Hynes.
