Two more people have been arrested related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both are still being held, the force said.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the injured in the event. A total of five individuals went to hospital for medical care and were later discharged.
Officers detained a man in his thirties for suspected theft and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of several people hurt by an irritating chemical thought to be pepper spray.
The attack - an event that authorities stated was isolated and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
