Two more people have been arrested in connection with a robbery at Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was one of the those hurt in the event. Five people were taken to the hospital for treatment and have since been discharged.
Police detained a 31-year-old man on suspicion of theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several people injured by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
