An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
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 suitcases upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and were later discharged.
Police detained a 31-year-old man on suspicion of theft and assault near the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be pepper spray.
The assault - which police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
