An additional two individuals have been arrested related to a theft at Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for medical care and were later discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were called at about 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical thought to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
