Police release surveillance photos of the man they say fired a shot into a Brooklyn high school.

Cops say the man seen here, sent a stray bullet flying into a classroom window at South Shore High School in Canarsie around 11:30 Tuesday morning.

They say it happened after he got into an argument with two other men across the street.

Four shots were fired, and one round went through fourth floor window of the school and into a blackboard.

The Department of Education says 17 students were in the room,  but no one was injured.

The man police are looking for was last seen wearing red jeans, a black hoodie, and was carrying a gray book bag.
