Two emergency personnel were injured after a person in mental crisis reportedly intentionally lit a house fire and caused a standoff with a SWAT team in Deerfield.
The Deerfield Police Department responded around 11:55 a.m. Wednesday to the 400 block of Deerfield Road for a report of a well-being check.
Officers were requested to check on a person residing at a house, police officials said. Officers arrived and made contact with the adult male subject.
They made threatening comments and retreated into the home where weapons were reported to possibly be present, police officials said.
Police officials said the assistance of numerous surrounding police agencies and the Northern Illinois Police Alarm System Emergency Services Team (NIPAS EST) was requested to assist.
Police officers began securing the immediate scene and the surrounding area.

A fire also occurred in a second-floor bedroom. Firefighters were able to extinguish the fire from the outside.
