Two more people have been arrested in connection with a robbery at London's Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, according to police.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for treatment and were later discharged.
Police arrested a man in his thirties on suspicion of theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals injured by a noxious substance thought to be pepper spray.
The assault - which police said was a standalone incident and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
