Two more people are now in custody related to a theft at London's Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to police.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a 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 Heathrow's Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance believed to be pepper spray.
The attack - an event that police said was isolated and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
