An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured during the incident. Five people went to hospital for medical care and were later released.
Police arrested a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT after reports came in regarding several people injured by a noxious substance thought to be pepper spray.
The assault - which authorities stated was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
