An MTA bus was struck by a stray bullet in Brooklyn Thursday afternoon, police said.

The B25 bus was hit by gunfire just sometime before 5:30 near the corner of Atlantic and New York avenues in Crown Heights, cops said.

The bus had seven people on board, including the driver, and no one was injured, sources said.

Police are searching the area for gray Jeep Wrangler, which they believe took off with the gunman inside.
