Two more people are now in custody related to a robbery at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both are still being held, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been released.
Police detained a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding several people injured by a noxious substance thought to be an irritant spray.
The attack - which police said was isolated and not being treated as an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
