Two more people are now in custody in connection with a theft at Heathrow Airport where over twenty individuals were injured by a substance believed 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 23-year-old woman was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for medical care and were later released.
Officers detained a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT following reports of a number of individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
