Two more people have been arrested in connection with a theft at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured during the incident. A total of five individuals went to hospital for treatment and have since been released.
Police arrested a 31-year-old man on suspicion of theft and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Police were alerted at about 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical believed to be pepper spray.
The assault - which police said was a standalone incident and not considered terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
