Two more people are now in custody in connection with a theft at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, according to police.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the injured in the event. Five people went to hospital for treatment and have since been discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding several individuals injured by a noxious substance believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
