Two more people are now in custody related to a theft at Heathrow Airport where 21 people were injured by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
These detentions come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for treatment and have since been released.
Police arrested 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.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance believed to be pepper spray.
The attack - which police said was isolated and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
