Two more people are now in custody in connection with a robbery at London's Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for treatment and have since been discharged.
Police arrested a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding several people injured by a noxious substance believed to be pepper spray.
The attack - which police said was isolated and not considered terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
