An additional two individuals are now in custody in connection with 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 Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was one of the those hurt in the event. A total of five individuals were taken to the hospital for medical care and have since been 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.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be pepper spray.
The assault - an event that police said was a standalone incident and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
