Two more people are now in custody related to a robbery at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to police.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was among the injured during the incident. A total of five individuals went to hospital for treatment and were later released.
Police detained a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several people injured by an irritating chemical thought to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
