Two more people are now in custody in connection with 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 man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
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 car park lift.
A three-year-old girl was among the injured in the event. Five people went to hospital for medical care and were later released.
Officers detained a man in his thirties on suspicion of robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding several individuals injured by a noxious substance believed to be pepper spray.
The assault - an event that authorities stated was isolated and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
