Two more people are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and were later discharged.
Police arrested a 31-year-old man for suspected theft and assault close to the location. He has since been released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT following reports of a number of people hurt by a noxious substance believed to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
