Two more people have been arrested in connection with a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to police.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to 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 were taken to the hospital for medical care and were later discharged.
Officers arrested a 31-year-old man for suspected theft and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of a number of people hurt 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 - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
