Someone shot a B.B. gun at an MBTA bus Saturday evening.
A spokesman for the MBTA confirmed that a Route 35 bus had been shot at.
It was not immediately known if the shooter had been arrested or how badly the bus had been damaged.
There were no injuries.
Last week, the windows of two school buses in Haverhill were shot out. Both contained students and one high school student was treated for a cut.
