An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the injured in the event. Five people were taken to the hospital for treatment and were later discharged.
Police 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 called at about 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance believed to be an irritant spray.
The assault - which authorities stated was isolated and not considered terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 car park for a short time.
