An additional two individuals are now in custody related to a theft at Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for treatment and were later released.
Police arrested a man in his thirties for suspected theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT following reports of several people injured by a noxious substance thought to be an irritant spray.
The attack - which police said was a standalone incident and not being treated as an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
