Two more people have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, according to police.
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 detained for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people were taken to the hospital for medical care and were later released.
Police arrested a 31-year-old man for suspected theft and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of a number of people hurt by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
