An additional two individuals are now in custody related to a robbery at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by police.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after a probe into an attack at the multi-level parking garage at Terminal 3 on 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 among the injured in the event. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police detained a man in his thirties for suspected theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding several people hurt by a noxious substance believed to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
