The mother of an intellectually disabled girl who was allegedly led from school grounds by three male students and sexually assaulted in a Starbucks bathroom and a nearby empty building filed a lawsuit Wednesday accusing Starbucks, Pittsburgh Public Schools and a property management company of negligence.

The lawsuit alleges that school personnel at Taylor Allderdice High School failed to provide adequate supervision and care of the girl during school hours and during transportation to and from school. It alleges that both the property management company 101 Kappa Drive Associates #1 and Starbucks managers were aware of the increasing crime issues near their businesses and failed to provide security or training for employees on how to respond to and report criminal activities.
