An additional two individuals are now in custody related to a theft at Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the injured during the incident. A total of five individuals went to hospital for medical care and were later discharged.
Police arrested a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding several individuals injured by a noxious substance thought to be pepper spray.
The assault - an event that police said was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
