An additional two individuals have been arrested related to a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was one of the injured during the incident. Five people were taken to the hospital for medical care and were later discharged.
Officers detained a 31-year-old man on suspicion of theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of a number of people hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - caused train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
