An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions come after an investigation into an assault at the multi-storey car park at Heathrow's 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 toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police arrested a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding a number of people injured by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 car park for a short time.
