Two more people have been arrested in connection with a theft at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was one of the those hurt in the event. Five people went to hospital for treatment and were later discharged.
Officers arrested a 31-year-old man on suspicion of theft and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of a number of individuals injured by an irritating chemical believed to be pepper spray.
The attack - which police said was isolated and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
