An additional two individuals 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 police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for medical care and were later released.
Officers detained a 31-year-old man for suspected theft and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT following reports of a number of people injured by a noxious substance thought to be pepper spray.
The assault - which police said was a standalone incident and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
