An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
The arrests come after an investigation 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 luggage after getting out of a parking garage elevator.
A toddler aged three was among the those hurt in the event. Five people went to hospital for treatment and have since been released.
Police detained a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people hurt by a noxious substance believed to be pepper spray.
The attack - an event that police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
