Two more people have been arrested related to a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured in the event. Five people went to hospital for treatment and were later discharged.
Police detained a 31-year-old man for suspected theft and assault near the location. He has since been released under investigation while inquiries continue.
Police were called at about 08:10 GMT following reports of a number of people injured by an irritating chemical believed 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 - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
