An additional two individuals have been arrested in connection with a theft 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 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. Five people were taken to the hospital for medical care and have since been released.
Officers arrested a man in his thirties on suspicion of theft and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding several people hurt by an irritating chemical thought to be pepper spray.
The assault - an event that police said was isolated and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
