An additional two individuals have been arrested related to a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was one of the injured in the event. Five people were taken to the hospital for medical care and were later released.
Officers arrested a man in his thirties on suspicion of robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of several people hurt by a noxious substance believed to be an irritant spray.
The attack - an event that police said was isolated and not considered terrorism - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
