Two more people have been arrested in connection with a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people were taken to the hospital for medical care and have since been discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of a number of individuals injured by a noxious substance believed to be pepper spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
