An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both are still being held, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for treatment and have since been released.
Police detained a man in his thirties on suspicion of theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 08:10 GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The attack - which authorities stated was isolated and not considered terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
