An additional two individuals have been arrested related to a robbery at Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the injured during the incident. Five people were taken to the hospital for medical care and were later released.
Officers detained a man in his thirties for suspected robbery and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of several people injured by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
