An additional two individuals have been arrested related to a theft at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 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 attack at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for treatment and were later released.
Police arrested a man in his thirties on suspicion of theft and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
