Two more people have been arrested in connection with a theft at London's Heathrow Airport where 21 people were injured by what is thought 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 robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests follow a probe into an assault at the multi-level parking garage 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 toddler aged three was among the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police arrested a man in his thirties on suspicion of theft and assault near the location. He has since been released under investigation as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
