Two more people are now in custody related to a theft at Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. Both individuals 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 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. Five people went to hospital for treatment and have since been released.
Officers detained a 31-year-old man on suspicion of theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of people hurt by an irritating chemical thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
