Two more people have been arrested related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, two women were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for medical care and have since been released.
Officers detained a man in his thirties for suspected robbery and assault near the location. He has since been released under investigation while inquiries continue.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding several people injured by a noxious substance thought to be pepper spray.
The assault - an event that police said was a standalone incident and not being treated as terrorism - 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.
