Two more people have been arrested in connection with a theft at London's Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers detained a man in his thirties for suspected robbery and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
