Two more people are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for treatment and have since been released.
Officers detained a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of several individuals hurt by a noxious substance believed to be an irritant spray.
The assault - which police said was isolated and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
