Two more people are now in custody related to a theft at London's Heathrow Airport in which 21 people were injured by a substance believed to be pepper 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 arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was one of the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been released.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the location. He has since been released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be an irritant spray.
The assault - an event that police said was isolated and not considered terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
