PHILADELPHIA - The family of a Lancaster County man who died after being repeatedly shocked with stun guns has filed a federal lawsuit against police and the device's manufacturer.

Sixty-one-year-old Robert Neill of Mount Joy died in 2010 after police arrived at his home after he called 911 about a stolen bike. Officers said he was unarmed but became aggressive and lunged at the officers.

The civil suit filed Wednesday in U.S. District Court alleges police used excessive force and Taser International designed an excessively dangerous device and failed to adequately train officers in its proper use.

Arizona-based Taser says its devices are generally safe and effective.
