Two more people are now in custody in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, 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 remain in custody, the force said.
These detentions follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people went to hospital for medical care and have since been discharged.
Police detained a 31-year-old man for suspected robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Police were called at about 08:10 GMT following reports of a number of individuals injured by a noxious substance believed to be pepper spray.
The assault - which police said was isolated and not considered terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
