An on-duty Sanitation worker was killed yesterday after being hit by a street sweeper. Police say that 43-year-old Stephen Frosch was performing maintenance work on a NYC Department of Sanitation street sweeper inside of a Sanitation Depot in Queens when another street sweeper, operated by a 33-year old Sanitation worker, was driving forward and struck him around 1 p.m., pinning him in between the two vehicles.

Frosh, who had been with the Sanitation Department since 1999, was pronounced dead at the scene. No arrests have been made and the investigation is ongoing. "Sanitation work is very dangerous and difficult work and we appreciate those who accept the call to duty," said Sanitation commissioner Kathryn Garcia in a statement. "Our hearts go out to the Frosch family on their loss."

"We are deeply saddened to learn of the loss of one of New York's Strongest today while on the job in service of our city," said Mayor de Blasio in a statement. "Our thoughts and prayers are with Steven Frosch's family—especially his wife and four children—as well as his friends and fellow sanitation workers."
