An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before 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 in the event. Five people went to hospital for medical care and were later discharged.
Police detained a man in his thirties on suspicion of theft and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding several people injured by an irritating chemical believed to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
