Two more people have been arrested in connection with a robbery at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. A total of five individuals went to hospital for treatment and were later released.
Officers arrested a 31-year-old man for suspected theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding a number of people injured by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
