Two more people have been arrested related to a robbery at Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of 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 Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for treatment and have since been released.
Police detained a man in his thirties on suspicion of robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at about 08:10 GMT after reports came in regarding several individuals injured by an irritating chemical believed to be pepper spray.
The assault - an event that police said was isolated and not considered terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
