An additional two individuals have been arrested in connection with a theft at Heathrow Airport where 21 people were injured by what is thought to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was among the injured during the incident. A total of five individuals went to hospital for treatment and have since been discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be an irritant spray.
The attack - which police said was isolated and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
