Airport officials confirmed that a United Airlines flight headed from Chicago to Frankfurt, Germany, made an emergency landing in Cleveland Friday afternoon, because of an unruly passenger, according to a report of Fox 8 News. According to Jackie Mayo, spokesperson for Cleveland Hopkins International Airport, the pilot diverted the flight to Cleveland after a passenger, who has been acting suspiciously on board, refused to comply with the flight crew\'s request to settle down. United Airlines said Flight 944, which was en route to Frankfurt from Chicago O\'Hare Airport, landed in Cleveland at about 5:30 p.m. (2130 GMT) Friday. Cleveland police officers and FBI detectives responded and removed the passenger from the plane. The suspect is in the custody of Cleveland police. Mayo said she did not know if he had been charged and was not aware of any injuries. The plane was then refueled and cleared to continue its journey to Frankfurt, but as of 8 p.m. (2400 GMT), the flight had still not departed from Hopkins International Airport.
