An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage 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 car park lift.
A three-year-old girl was among the injured in the event. Five people went to hospital for medical care and were later discharged.
Police arrested a 31-year-old man for suspected robbery and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of several people injured by an irritating chemical believed to be pepper spray.
The assault - which police said was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
