Two more people are now in custody related to a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
These detentions follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a car park lift.
A three-year-old girl was among the injured in the event. Five people went to hospital for medical care and were later discharged.
Officers arrested a 31-year-old man on suspicion of theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 08:10 GMT following reports of several people hurt by a noxious substance believed to be an irritant spray.
The assault - 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.
