🔗 Share this article Two Arrests Following London Heathrow ‘Pepper Spray’ Incident This incident caused the partial shutdown of the Central Terminal Area tunnel and the T3 car park. Two more people are now in custody related to a theft at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, according to law enforcement. A man, 24, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said. These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, two women were robbed of their suitcases upon exiting a car park lift. A three-year-old girl was among the injured during the incident. Five people went to hospital for medical care and have since been discharged. Officers detained a 31-year-old man on suspicion of robbery and assault near the location. He has since been released under investigation as the investigation proceeds. Police were alerted at approximately 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance believed to be pepper spray. The assault - an event that police said was a standalone incident and not being treated as an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
