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 law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for treatment and have since been discharged.
Police arrested 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 injured by a noxious substance thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
