A standoff between police and a man, who was armed with a knife and threatening suicide, ended peacefully overnight in Crystal Lake, authorities said.

The Crystal Lake Police Department responded around 1:36 a.m. Thursday to the 200 block of Uteg Street for a report of a person with a knife call.

Crystal Lake Deputy Police Chief Thomas Kotlowski said that an adult male resident was armed with a knife and contemplating suicide.

Officers made contact with the man, who refused police entry to the residence and declined any medical attention.

“Concerned for his well-being, officers maintained contact with the man and encouraged him to allow us to provide the assistance he may need. He adamantly refused any assistance,” Kotlowski said.

The Northern Illinois Police Alarm System Emergency Services Team (NIPAS EST), which is a special tactical squad comprised of officers from multiple police agencies trained for situations such as this.

SWAT team members detained the man following a four-hour standoff that ended around 5 a.m. The man was taken into custody without incident after he stepped outside of his apartment.

He was transported to a local hospital for an evaluation. No injuries were reported to anyone involved.

“Given this was a mental health crisis event and not criminal in nature, no further information will be provided out of respect for the resident’s privacy,” Kotlowski said, adding that no criminal charges will be filed.

“We would like to thank those EST members who responded, as well as the several area police agencies that sent officers to support the operation,” the Crystal Lake Police Department said.
