A man was killed on the runway at Moscow's largest airport when he was hit by a plane that was taking off, Russian investigators said Wednesday.

Russian news agencies quoted sources as saying the man was on a stopover and had earlier picked a fight on board his flight from Spain. 

The 25-year-old somehow ended up on the runway where "a Boeing 737 plane inflicted deadly injuries on him during takeoff," the Russian Investigative Committee said.

The incident occurred in Sheremetyevo airport at around 8 pm on Tuesday as the plane was taking off on a flight to Athens.

The head of Russia's aviation watchdog Alexander Neradko said that the plane was operated by Russian flagship carrier Aeroflot. 

Investigators said in a video posted on Twitter that they found down from the man's coat and a shoelace among the fragments scattered on the runway. No official criminal probe has been launched yet.

Sheremetyevo Airport did not immediately respond to a request for comment.

Russian news agencies said the man had been escorted by police in Sheremetyevo to the boarding gate for his connecting flight, but then walked away instead of boarding a bus to the plane.

Aeroflot, which flies from Sheremetyevo, said on its website Wednesday that a number of flights have been rescheduled as one of the three runways was closed.
