Two more people are now in custody related to a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was arrested in Lambeth for suspected theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was one of the injured during the incident. A total of five individuals were taken to the hospital for medical care and were later discharged.
Officers arrested a man in his thirties on suspicion of robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several people injured by a noxious substance thought to be pepper spray.
The assault - an event that police said was isolated and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
