Two EMS workers were robbed at gunpoint after responding to a call for help at a Brooklyn apartment building, police said.

The unsuspecting first responders went to 330 Frost St. in East Williamsburg around 2:30 a.m. Saturday after getting a call about someone with a “medical condition” at the 7-floor, 56 unit city-owned Cooper Park Houses, cops said.

When they got to the sixth floor, they were met by a man with a gun who took their Tac bags and radios. The robber fled the scene and the workers were not harmed, police said.

Anyone with information in regard to this incident is asked to call the NYPD’s Crime Stoppers Hotline at 1-800-577-TIPS (8477).
