Two more people have been arrested related to a robbery at London's Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to 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 arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests follow a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals went to hospital for medical care and were later released.
Police arrested a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several people injured by a noxious substance thought to be pepper spray.
The assault - an event that police said was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
