A Boston Police officer arrived at the scene and applied a tourniquet to the EMT’s leg. She was rushed to MGH and is recovering after surgery. The second EMT, a 10-year veteran, was treated and released.

“These EMTs did not deserve this,” Boston Police Commissioner William Gross said. “Every day they go out and they help people, they save lives, they did not deserve to be attacked.”
