Two more people have been arrested following a "pepper spray" incident at London's Heathrow Airport
The incident took place shortly after 8am on Sunday, when two women were allegedly robbed of their suitcases after leaving the car park lift within the airport's Terminal 3 building.
The alleged robbers then sprayed them with what is believed to be pepper spray, which affected others nearby.
Armed police responded and arrested a 31-year-old man on suspicion of robbery and assault close to the scene on Sunday. He was released under investigation while enquiries continue.
Now, a 24-year-old man in Lambeth has been arrested on suspicion of robbery and assault and a 23-year-old woman on suspicion of conspiracy to commit robbery, the Metropolitan Police said.
The pair remain in custody.
London Ambulance Service attended the scene and treated 21 people, including a three-year-old girl, who had been hit with the noxious spray in a multi-storey car park.
Five people were taken to hospital. Their injuries are not believed to be life-changing or life-threatening.
They have all since been discharged.
The London Fire Brigade also attended, a spokesperson said.
