An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage after getting out of 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 have since been discharged.
Police detained a 31-year-old man on suspicion of theft and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance believed to be pepper spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
