An additional two individuals have been arrested related to a theft at Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the injured during the incident. A total of five individuals went to hospital for treatment and have since been released.
Officers detained a man in his thirties on suspicion of robbery and assault near the location. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding several people injured by an irritating chemical thought to be pepper spray.
The attack - an event that police said was isolated and not considered an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
