A Pair of Detentions Following Heathrow Irritant Spray Attack

Two more people have been arrested in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to police.

A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.

These detentions come after an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage upon exiting a car park lift.

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

Officers arrested a man in his thirties for suspected robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.

Authorities were called at approximately 8:10 in the morning GMT following reports of a number of people hurt by an irritating chemical believed to be pepper spray.

The assault - an event that police said was isolated 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.
