An additional two individuals have been arrested related to a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both 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 on Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt in the event. A total of five individuals went to hospital for treatment and have since been discharged.
Officers detained a 31-year-old man on suspicion of robbery and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of several people injured by a noxious substance thought to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
