An additional two individuals have been arrested related to a theft at London's Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions follow a probe 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 suitcases after getting out of a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for treatment and were later released.
Officers arrested a man in his thirties on suspicion of robbery and assault near the location. He has since been released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding several people injured by an irritating chemical believed to be pepper spray.
The assault - which authorities stated was isolated and not considered terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
