Two more people have been arrested in connection with a theft at Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for medical care and have since been released.
Police detained a man in his thirties for suspected robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of a number of people injured by an irritating chemical thought to be an irritant spray.
The attack - which authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
