An additional two individuals are now in custody related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
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 are still being held, the force said.
The arrests come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers detained a man in his thirties on suspicion of theft and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not being treated as terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
