Two more people are now in custody related to a robbery at Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, 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. A total of five individuals were taken to the hospital for medical care and were later discharged.
Police detained a man in his thirties for suspected theft and assault close to the location. He has since been released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
