A Pair of Arrests in the Aftermath of Heathrow Irritant Spray Attack

An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, according to police.

A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.

The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.

A three-year-old girl was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.

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

Police were called at approximately 08:10 GMT following reports of a number of people injured by a noxious substance thought to be pepper spray.

The assault - which police said was a standalone incident and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
