An additional two individuals have been arrested related to a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals went to hospital for medical care and have since been discharged.
Officers detained a 31-year-old man on suspicion of theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Police were alerted at approximately 08:10 GMT following reports of several people injured by an irritating chemical believed to be an irritant 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 temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
