Two more people are now in custody in connection with 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 man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the injured in the event. A total of five individuals went to hospital for treatment and were later released.
Police arrested a man in his thirties on suspicion of robbery and assault near the location. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
