An additional two individuals have been arrested related to a theft at Heathrow Airport where 21 people were injured by what is thought to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people were taken to the hospital for medical care and have since been discharged.
Police arrested a 31-year-old man on suspicion of robbery and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at about 8:10 in the morning GMT following reports of several people injured by a noxious substance thought to be pepper spray.
The attack - which authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
