An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions come after an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases 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 were later discharged.
Officers detained a 31-year-old man on suspicion of theft and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding several people injured by an irritating chemical thought to be pepper spray.
The assault - which police said was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
