An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was one of the those hurt in the event. Five people were taken to the hospital for treatment and have since been discharged.
Police detained a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of several individuals hurt by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
