The drill, held Saturday, at Fox Lane High School, including officers from Bedford, Westchester County, North Castle, Pound Ridge and Yorktown police departments.
Fire departments included Bedford, Bedford Hills, and Pound Ridge. EMS agencies were Katonah-Bedford Hills and Pound Ridge Volunteer Ambulance Corps.
During the training, more than 50 police, fire, and EMS members, along with 20 volunteer victims took part in reality-based training to simulate an active shooter event.
Volunteers from The Harvey School art department assisted in creating artificial, lifelike injuries on victims.
Bedford Police Department has been hosting and conducting active shooter training on a regular basis since 2013.
In 2016 the training was expanded to include local EMS and fire departments as they have become an integral part of active shooter response.
"The partnerships between Police, Fire, EMS and local school districts allow us to provide the best possible training for our officers, as well as mutual aid agencies in the region," said Bedford Police Chief Melvin Padilla.
