Two more people are now in custody in connection with a theft at Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and were later released.
Officers arrested a 31-year-old man for suspected theft and assault near the location. He has since been released under investigation while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding several individuals injured by an irritating chemical thought to be pepper spray.
The assault - an event that authorities stated 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 car park for a short time.
