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 law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. A total of five individuals went to hospital for treatment and have since been released.
Police arrested a man in his thirties on suspicion of theft and assault close to the location. He has since been released under investigation as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT following reports of several individuals injured by a noxious substance believed to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
