Passengers at O’Hare airport got an eyeful on Tuesday afternoon as a man was spotted shouting and taking his clothes off on the tarmac.

Paramedics have taken the man to the hospital for a mental evaluation after the Chicago Police said he was having a mental health crisis.

A video was posted by ORD Airport Insider of the man walking down the tarmac.

Earlier today, a naked male passenger was detained at Gate C10 at Chicago – O’Hare’s Terminal 1 walking around on the ramp. (Not my video, submitted by a follower who’d rather remain anonymous) #ORDscanner #ORDairportops pic.twitter.com/fhVP8KhZJR

They also posted photos of the man being held on the tarmac, along with more information on the situation.

Multiple witnesses say he walked off a Delta flight at Terminal 2, but that hasn’t been confirmed. He was quickly apprehended by airport authorities. #ORDairportops #ORDscanner pic.twitter.com/wIKVlsLZtk

Yet another photo of our naked trespasser today. I can’t believe he walked all the way from E12 to C10 before he was finally detained. I hope he gets the help he needs. #ORDscanner #ORDairportops pic.twitter.com/Amd44oLchj

Workers at O’Hare even posted a video on their youtube channel of the man on the tarmac.

No one’s quite sure how he got passed security.
