An additional two individuals have been arrested in connection with a theft at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was one of the injured in the event. Five people went to hospital for treatment and were later discharged.
Police arrested a man in his thirties for suspected robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT after reports came in regarding a number of people injured by a noxious substance believed to be pepper spray.
The attack - which police said was a standalone incident and not being treated as an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
