An additional two individuals have been arrested related to a theft at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers arrested a man in his thirties for suspected theft and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was isolated and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
