Two more people are now in custody in connection with a theft at London's Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft 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.
These detentions follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the those hurt in the event. A total of five individuals went to hospital for medical care and were later released.
Officers detained a man in his thirties on suspicion of robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were called at about 08:10 GMT following reports of several individuals injured by a noxious substance believed to be pepper spray.
The attack - 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 Central Terminal Area tunnel and the Terminal 3 car park for a short time.
