Police are trying to determine who threw a rock through a Manassas school bus carrying 10 children.
It happened Thursday just before 5 p.m. when the bus was making a right turn on to Wharton Court from Confederate Trail, Manassas Police reports show.
The rock broke a bus window and landed on a seat. None of the passengers were seated near where the rock landed and no injuries were reported.
Police said neither the bus driver nor the students saw who threw the rock.
No arrests have been made.
Throwing a missile into an occupied vehicle is a felony offense in violation of section 18.2-154 of the Virginia Code, Manassas Police said.
