Two more people have been arrested related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of theft 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.
The arrests follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for treatment and were later discharged.
Police arrested a man in his thirties for suspected robbery and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of a number of individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
