An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected 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 assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police arrested a 31-year-old man on suspicion of robbery and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance believed to be pepper spray.
The attack - which police said was isolated and not considered an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 car park briefly.
