Two more people have been arrested in connection with a robbery at London's Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was detained on suspicion of 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 Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for medical care and have since been released.
Police detained a man in his thirties for suspected theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of several people hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
