A Pair of Arrests in the Aftermath of London Heathrow ‘Pepper Spray’ Attack

Two more people are now in custody related to a theft at Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.

A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.

These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, two women were robbed of their suitcases upon exiting a parking garage elevator.

A three-year-old girl was one of the injured during the incident. Five people went to hospital for medical care and were later discharged.

Police arrested a 31-year-old man for suspected robbery and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.

Police were alerted at about 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be pepper spray.

The attack - an event that police said was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
