Two Detentions Following London 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 pepper spray, according to law enforcement.

A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.

These detentions come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.

A toddler aged three was among the those hurt in the event. Five people went to hospital for medical care and have since been discharged.

Police arrested a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.

Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding several people hurt by an irritating chemical thought to be pepper spray.

The attack - an event that police said was isolated 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 for a short time.
