An additional two individuals have been arrested related to a theft at Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. A total of five individuals went to hospital for medical care and have since been released.
Officers arrested a 31-year-old man on suspicion of theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of a number of individuals injured by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was isolated and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
