An additional two individuals have been arrested related to a theft at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Police detained a man in his thirties for suspected robbery and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance believed to be pepper spray.
The attack - an event that police said was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
