WEST HARTFORD, Conn. (AP) A lawsuit claims administrators at a middle school near Hartford allowed an autistic student to be sexually assaulted and then tried to cover it up.

WVIT-TV reports the lawsuit was filed Monday against the West Hartford Board of Education claiming the district allowed a student to bully, sexually assault and harass a 13-year-old autistic student at King Philip Middle School.

The suit says administrators promised to separate them after a 2013 incident, but continued to let the boys in the locker room unsupervised. It claims the child tried to sexually assault the other for weeks until doing so in November.

The suit says the school then tried to cover up the negligence and deny responsibility.
