Ex-NFL Cheerleader -- Banned from School of Alleged Victim

Molly Shattuck -- the 47-year-old former cheerleader accused of raping a 15-year-old boy -- has been barred from the alleged victim's school ... which is the same school her 3 kids attend.

McDonogh School Headmaster Charles W. Britton addressed the scandal in a letter to parents, saying he reported the allegation to the Baltimore County Police Department as soon as it was brought to his attention.

Britton sent the letter to inform parents Shattuck -- a former Baltimore Ravens cheerleader -- had been barred from the school, and additional security measures were now in place.
