Four "unruly" passengers on board a Northwest Airlines flight from Amsterdam to Detroit were questioned by US Customs and Border Protection officials on Wednesday after the airline crew reported they were not complying with "crew member instructions".
The passengers in question were quizzed by CBP Officers and later released.
The Transportation Security Administration (TSA) said it was "notified of unruly passengers on board Northwest Flight 243 from Amsterdam's Schiphol International Airport to Detroit Wayne County International Airport.
TSA monitored the flight, which landed "without incident".
The four passengers on the flight "did not comply with crew member instructions and out of an abundance of caution, the crew requested authorities meet the flight upon arrival," the airline said in a statement.
The plane had 245 passengers and 12 crew members on board at that time.
TSA officials along with representatives from US Customs and Border Protection, Federal Air Marshals and local law enforcement received the flight when it landed.
After the flight landed this afternoon, it was held in an area at a safe distance from the McNamara Terminal while federal authorities investigated "behaviour thought to be suspicious".
The plane was later cleared to taxi to the gate.
