Two more people are now in custody in connection with a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. Five people went to hospital for medical care and have since been discharged.
Police arrested a man in his thirties for suspected robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of several people injured by an irritating chemical believed to be pepper spray.
The attack - an event that police said was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
