Two more people have been arrested in connection with a robbery at Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt in the event. Five people went to hospital for medical care and have since been released.
Police arrested a 31-year-old man on suspicion of theft and assault near the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of several individuals hurt by an irritating chemical thought to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
