WICHITA, Kan (AP) – A 62-year-old Wichita man who claimed to be a ninja is being evaluated after a three-hour standoff with Sedgwick County deputies in which SWAT team sent tear gas into the home.

The Wichita Eagle reports deputies were trying to take the man into custody around 4 pm Wednesday after receiving a court order because he was believed to be a threat to himself or others.

When deputies tried to take him into custody, the man started waving a stick at them and backed into the home, where deputies believed he might have weapons.

A SWAT team used tear gas inside the home just before 7:30 pm after sheriff’s negotiators were unable to coax the man outside.

The man surrendered and was taken to a hospital for evaluation.
