Two more people are now in custody related to a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, as stated by police.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
These detentions come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers detained a 31-year-old man on suspicion of theft and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical believed to be pepper spray.
The assault - an event that police said was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
