A 62-year-old man was taken into custody for a mental evaluation early Tuesday morning after an incident in northern Lawrence involving a hand grenade that later was discovered to be a “dummy” weapon.

According to Lawrence Police Sgt. Ted Bordman, police were called to the 100 block of North Michigan Street just after midnight because a 62-year-old man had been making suicidal comments to another person in the area and was holding an apparent hand grenade. The concerned person called police.

Officers set up a perimeter around the residence. Bordman said the 62-year-old man was standing in the front yard holding the grenade. The man was not making threats.

Officers got him to drop the grenade and took him into custody without incident. Bordman said officers recovered the grenade from the yard and determined it was a “dummy” weapon.

The 62-year-old man was taken into custody and transported to Lawrence Memorial Hospital for a mental health screening. No criminal charges were filed against the suspect Tuesday.

No one was injured during the incident.
