Two more people have been arrested in connection with a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for medical care and were later discharged.
Police detained a 31-year-old man for suspected robbery 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 a number of individuals hurt by an irritating chemical believed to be pepper spray.
The assault - which police said was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
