An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, the force said.
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, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the injured in the event. A total of five individuals went to hospital for medical care and were later released.
Police arrested a man in his thirties for suspected theft and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 8:10 in the morning GMT following reports of a number of people injured by a noxious substance believed to be pepper spray.
The attack - which police said was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
