Two more people are now in custody related to a theft at Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the injured during the incident. Five people were taken to the hospital for medical care and have since been discharged.
Officers detained a 31-year-old man for suspected robbery and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding several people hurt by a noxious substance believed to be pepper spray.
The assault - an event that authorities stated was isolated and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
