Two more people 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 police.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, two women were robbed of 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 medical care and were later released.
Officers arrested a man in his thirties for suspected theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT following reports of several individuals injured by a noxious substance believed to be pepper spray.
The assault - an event that police said was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
