The Boston Police Department reports a Mascot Street youngster started up his mother's car and put it in revers Wednesday morning - causing it to roll across the street and slam into a neighbor's house at 64 Mascot:

"Officers noted serious damage to both the rear body of the motor vehicle and the porch. The vehicle had struck the house with such force that it had appeared to cause structural damage to the foundation of the home. ... Officers spoke to the owner of the home who stated that he was inside his home when he heard a loud crash. The home owner further states that when he went outside to investigate the noise, he observed a car crashed into his porch and a young boy running away from the scene."

The boy appeared uninjured but was taken to Boston Medical Center as a precaution, police say.
