An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was among the injured in the event. Five people went to hospital for medical care and were later discharged.
Police arrested a man in his thirties on suspicion of robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of several people hurt by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
