Two more people have been arrested in connection with a theft at Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. A total of five individuals went to hospital for treatment and were later discharged.
Officers arrested a man in his thirties on suspicion of robbery and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of several people hurt by an irritating chemical believed to be pepper spray.
The attack - which police said was isolated and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
