Two more people are now in custody related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody 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. Both individuals are still being held, the force said.
These detentions follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was one of the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police detained a 31-year-old man for suspected robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding a number of individuals injured by an irritating chemical believed to be pepper spray.
The attack - an event that police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
