You might have seen a commotion in the 300 block of South 10th Street in Quincy Thursday morning.
Police responded to reports of a mentally disturbed naked male in the yard of a residence.
QPD says when the first officer arrived, the man retreated inside his residence to get a samurai sword.
The man then came back outside and began swinging the sword in the direction of some bystanders.
Officers used a taser to subdue the man and then took him to Blessing Hospital for treatment.
No one was hurt.
No criminal charges are anticipated.
