Two more people are now in custody related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-storey car park 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 one of the injured during the incident. Five people went to hospital for medical care and have since been released.
Police detained a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by a noxious substance believed to be pepper spray.
The assault - which authorities stated was isolated and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
