Two more people are now in custody related to a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, the force said.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people were taken to the hospital for treatment and have since been released.
Officers detained a 31-year-old man for suspected robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were alerted at approximately 08:10 GMT following reports of several individuals hurt by a noxious substance believed to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
