An additional two individuals are now in custody related to a robbery at Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured during the incident. Five people went to hospital for treatment and were later discharged.
Officers arrested a man in his thirties for suspected theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals injured by a noxious substance believed to be pepper spray.
The attack - which police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
