A Seattle flight bound for Beijing turned around Thursday evening after a passenger assaulted a flight attendant and attempted to get into the cockpit.
There is no information to suggest there is a security threat, according to Perry Cooper, a Sea-Tac Airport spokesperson.
Delta Flight 129 left the airport just after 5 p.m., and about 45 min into the flight a First Class passenger assaulted a flight attendant.
Several passengers help subdue the suspect, and the suspect was restrained on board, according to Delta.
The flight turned around and landed back at Sea-Tac around 7:10 p.m. without incident where police took the suspect into custody.
Two passengers and one crew member sustained minor injuries.
The Port Police is working with the FBI.
The flight is scheduled to re-depart for Beijing later this evening.
