An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
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. They both remain in custody, the force said.
The arrests 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 had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for medical care and were later discharged.
Police detained a 31-year-old man on suspicion of robbery and assault near the scene. He was subsequently released under investigation while inquiries continue.
Police were called at about 08:10 GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be pepper spray.
The assault - an event that police said was isolated and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
