Two more people are now in custody in connection with a robbery at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage upon exiting a parking garage elevator.
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 arrested a 31-year-old man for suspected robbery and assault close to the location. He has since been released under investigation while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not being treated as terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
