Chicago Police on Tuesday afternoon apprehended a naked male passenger who had wandered onto the tarmac of O’Hare International Airport. The unidentified man was taken to a hospital for psychiatric evaluation, according to the Chicago Sun-Times.

Chicago Police told International Business Times that there are no charges pending against the man and that he was suffering through "a mental health episode."

The Chicago Department of Aviation had no official comment or update for IBT as to how the man made it onto the tarmac. Police said it is an ongoing investigation.

A video was posted on Twitter showing the man roaming around the tarmac. He had walked off a Delta flight, according to a tweet from ORD Airport Insider.

Another tweet noted that the man had walked from Gate E12 to C10.

Police apprehended the man, while he wore a safety vest around his waist. He was taken to Resurrection Medical Center.

The incident at O'Hare comes days after a similar incident at Moscow Domodedovo Airport.

On Saturday, a man passed through registration for a Ural Airlines flight when he then stripped off his clothes. Witnesses said he ran naked onto the jet bridge, screaming that "clothing impaired the aerodynamics of the body" and that he "flies with more agility when undressed."

Witnesses also pointed out that the man did not appear drunk when he did this. Police detained the man and brought him to the airport’s medical room before being taken to a professional medical facility.
