A man swinging a knife and approaching motorists in Montgomery County, Maryland, on Sunday was subdued using a stun gun.

It happened around 6:45 p.m. on the intersection of Rockville Pike and Grosvernor Lane in Bethesda.

That’s where police said the man with a blanket wrapped around his head was approaching drivers with a knife.

“It appeared the man was having a severe, possibly psychotic, episode and was extremely delusional,” police said in a news release.

Officers blocked traffic and tried to talk with the man, while staying safely at a distance. They stunned him when attempts to de-escalate the situation failed.

He was taken to the hospital, where he told police that he had a history of mental illness and had previously taken amphetamines.

There were no injuries.
