An additional two individuals are now in custody related to a theft at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people went to hospital for treatment and have since been released.
Officers detained a man in his thirties for suspected robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of a number of people hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was isolated and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
