A Pair of Detentions Following London Heathrow Irritant Spray Incident

An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.

A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.

The arrests come after an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.

A three-year-old girl was among the injured during the incident. Five people went to hospital for treatment and were later discharged.

Police arrested a 31-year-old man for suspected robbery and assault near the location. He was subsequently released under investigation while inquiries continue.

Authorities were called at about 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be pepper spray.

The attack - which police said was isolated and not considered terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
