An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
These detentions follow a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, two women were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for medical care and were later released.
Police detained a man in his thirties on suspicion of robbery and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities 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 an irritant spray.
The attack - which authorities stated 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 parking facility briefly.
