🔗 Share this article A Pair of Arrests in the Aftermath of Heathrow ‘Pepper Spray’ Incident This incident caused the partial shutdown of the CTA tunnel and the T3 parking area. An additional two individuals are now in custody in connection with 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 woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, the force said. These detentions follow a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases upon exiting a car park lift. A three-year-old girl was among the injured in the event. A total of five individuals went to hospital for treatment and were later released. Police arrested a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released under investigation while inquiries continue. Police were alerted at about 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance thought to be an irritant spray. The attack - an event that police said was isolated and not being treated as terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
