Two more people have been arrested in connection with a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was one of the those hurt in the event. Five people went to hospital for medical care and were later released.
Police arrested a 31-year-old man on suspicion of robbery and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of people injured by a noxious substance believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
