A BB-gun shooter opened fire at an MTA bus with about 15 passengers on board in an apparent random attack during the Friday morning rush, cops said. 

The suspect shot at the BxM7 bus at Bruckner Boulevard and Morrison Avenue in Soundview around 8:15 a.m., police said. 

An unknown number of pellets struck the driver’s side window, police said. 

No one was hurt, authorities said. 

Preliminarily, the shooting appeared random, cops said. 

No arrests have been made, and no suspect description is yet available.
