Two more people are now in custody in connection with a robbery at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the injured during the incident. Five people were taken to the hospital for treatment and have since been released.
Officers detained a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT following reports of several people injured by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
