Two Detentions Following London Heathrow Irritant Spray Attack

Two more people have been arrested in connection with a robbery at Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, according to law enforcement.

A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both are still being held, the force said.

The arrests follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a car park lift.

A three-year-old girl was among the those hurt in the event. Five people were taken to the hospital for treatment and have since been released.

Officers arrested a man in his thirties on suspicion of theft and assault close to the location. He has since been released under investigation as the investigation proceeds.

Police were called at approximately 8:10 in the morning GMT following reports of several individuals injured by a noxious substance believed to be an irritant spray.

The attack - which authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
