Two Arrests Following Heathrow Irritant Spray Incident

An additional two individuals are now in custody related to a theft at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, according to police.

A man, 24, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, the force said.

These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.

A toddler aged three was among the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and have since been discharged.

Officers detained a 31-year-old man on suspicion of theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.

Authorities were called at about 08:10 GMT following reports of a number of individuals hurt by an irritating chemical believed to be pepper spray.

The assault - which police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
