ARLINGTON, Va. (WTVR) – The FBI is investigating an incident on-board a Delta Airlines plane set to take off from Reagan National Airport Friday.
Delta Airlines says a federal officer noticed four people acting suspicious. An FBI spokesperson told the Huffington Post that some passengers asked to use the restroom while the plane was on the runway.
According to the Huffington Post, there was a language barrier between the suspicious passengers and the flight crew, making the plane return to the gate.
The four passengers were removed from the plane and are undergoing investigation.
The plane landed in Detroit without any further problems.
