Two more people are now in custody related to a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured in the event. Five people went to hospital for treatment and were later discharged.
Officers arrested a man in his thirties on suspicion of theft and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT following reports of a number of people hurt by a noxious substance thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
