Two more people are now in custody related to a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
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 detained a 31-year-old man for suspected robbery and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding several individuals injured by a noxious substance thought to be an irritant spray.
The assault - an event that police said was isolated and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
