Two more people are now in custody in connection with a robbery at Heathrow Airport where 21 people were injured by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for medical care and were later discharged.
Officers arrested a 31-year-old man for suspected robbery and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding a number of individuals injured by an irritating chemical thought to be pepper spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
