Two more people have been arrested related to a robbery at London's Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
These detentions come after an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, 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 during the incident. Five people were taken to the hospital for medical care and were later released.
Police arrested a man in his thirties on suspicion of theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
