A knife-wielding man attacked three people in an apparently random assault on a downtown Seattle street early Tuesday — then stripped naked as he tried to evade cops, according to authorities and reports.

The unidentified suspect waved his blade at three men outside a Nordstrom clothing store near Sixth Avenue and Olive Way around 10 a.m. local time, the Seattle Police Department tweeted.

A traffic-camera image tweeted by a reporter for ABC Radio affiliate KOMO News shows cops crowded in the street around the downed suspect — who appears to be in the buff.

Cops said that the man was clothed when he attacked, but stripped down as he fled, adding that his “clothing and knife [were] recovered in the area.”

Three men were injured, though authorities wouldn’t immediately say whether all were stabbed.

Two of the victims, 77 and 75, were taken to an area hospital in stable condition, while the third, 55, declined medical attention.

“We do believe that this was an unprovoked and random attack, so it is very concerning for us,” said a police spokesman in a press briefing at the scene.

Charges are pending against the suspect, whose name was not immediately disclosed by police.
