Two Arrests in the Aftermath of London Heathrow Irritant Spray Attack

An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.

A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.

These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.

A three-year-old girl was one of the injured in the event. A total of five individuals went to hospital for treatment and were later discharged.

Police arrested a 31-year-old man on suspicion of theft and assault close to the location. He has since been released pending further inquiries while inquiries continue.

Authorities were called at about 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical believed to be pepper spray.

The assault - an event that authorities stated was a standalone incident and not considered terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
