MARYSVILLE, Wash. (AP) -- Six middle school boys in Marysville, Wash., have been barred from school as police and school district officials investigate what is described as a sexually motivated assault on a 13-year-old girl on a school bus.
Marysville School District Superintendent Larry Nyland tells the Daily Herald (http://is.gd/bQEL5V ) that the March 1 incident was captured on surveillance video from a bus camera. The district did not learn about it until the next day. The case involves Marysville Middle School students aged 11 to 15.
Nyland and police Cmdr. Robb Lamoureux refused to describe exactly what is alleged to have happened. Nyland says the bus driver may not have known what was going on.
KOMO-TV reports the girl was not injured.
Lamoureux says police are conducting a full criminal investigation. He says criminal charges are possible. The district is investigating also.
Parents were notified Thursday by letter.
Marysville is about 30 miles north of Seattle.
