A thrown rock damaged a Boston EMS ambulance as it traveled past an infamous homeless encampment in the city, according to a report.

A Boston EMS captain was responding to a shooting in Roxbury around 7:30 p.m. on October 19 with its lights and sirens activated when the rock was thrown, WCVB reported.

The 40-year EMS veteran was not hurt, but the cracked windshield forced the ambulance out of service.

Matthew Anderson, president of the Boston Police Patrolman’s Association’s EMS Division, condemned the action. “Our providers were assaulted over 150 times last year, leaving some with permanent bodily injury and disfigurement. Violence against EMS not only places our staff at risk but also the patients we are responding to care for.”
