Two more people are now in custody in connection with a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases 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 have since been released.
Police detained a 31-year-old man on suspicion of 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 people hurt by a noxious substance believed to be an irritant spray.
The assault - which police said was a standalone incident and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
