Two more people have been arrested in connection with a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was among the those hurt in the event. Five people were taken to the hospital for medical care and have since been discharged.
Police detained a 31-year-old man for suspected theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT following reports of several individuals injured by a noxious substance believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the T3 car park briefly.
