An additional two individuals have been arrested related to a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for treatment and were later discharged.
Police arrested a 31-year-old man for suspected robbery and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding several people injured by a noxious substance thought to be pepper spray.
The assault - which authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
