Two Arrests in the Aftermath of Heathrow Irritant Spray Attack

An additional two individuals have been arrested related to a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by police.

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

The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.

A toddler aged three was one of the injured during the incident. Five people went to hospital for treatment and have since been released.

Officers arrested a 31-year-old man on suspicion of robbery and assault close to the location. He was subsequently released under investigation while inquiries continue.

Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several people hurt by a noxious substance thought to be an irritant spray.

The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
