An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for medical care and were later released.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of several people injured by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
