An additional two individuals are now in custody related to a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people went to hospital for medical care 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.
Authorities were called at about 08:10 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 an act of terror - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
