An additional two individuals have been arrested related to a theft at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, two women were robbed of their luggage after getting out of 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 discharged.
Police arrested a 31-year-old man for suspected theft and assault near the scene. He has since been released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was isolated and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the T3 car park for a short time.
