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 an irritant spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Officers arrested a man in his thirties for suspected robbery and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of a number of individuals injured by a noxious substance believed to be an irritant spray.
The attack - which authorities stated was isolated and not considered an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 car park briefly.
