An additional two individuals are now in custody related to a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for medical care and were later discharged.
Police detained a man in his thirties on suspicion of theft and assault near the location. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT following reports of a number of individuals hurt by a noxious substance believed to be an irritant spray.
The assault - an event that police said was isolated and not considered terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
