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 an irritant spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been released.
Police detained a man in his thirties on suspicion of robbery and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of a number of individuals injured by a noxious substance believed to be an irritant spray.
The assault - which authorities stated was isolated and not considered terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
