Two more people have been arrested related to a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected 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 Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. A total of five individuals went to hospital for treatment and have since been discharged.
Officers arrested a man in his thirties for suspected robbery and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding several people hurt by a noxious substance thought to be an irritant spray.
The assault - which authorities stated was isolated and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
