An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport where 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 for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both are still being held, the force said.
These detentions come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was one of the injured in the event. Five people went to hospital for treatment and were later discharged.
Officers arrested a man in his thirties for suspected robbery and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT following reports of several individuals injured by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
