Two more people are now in custody related to a robbery at London's Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, two women were robbed of 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 treatment and were later released.
Police arrested a man in his thirties on suspicion of robbery and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of people injured by a noxious substance thought to be pepper spray.
The attack - an event that police said was a standalone incident and not considered terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
