An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions come after an investigation 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 after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for treatment and were later discharged.
Police arrested a 31-year-old man for suspected robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding several individuals injured by a noxious substance believed to be pepper spray.
The attack - which police said was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
