Two more people have been arrested in connection with a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both are still being held, the force said.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for treatment and have since been released.
Officers arrested a man in his thirties for suspected robbery and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of a number of individuals hurt by a noxious substance thought to be pepper spray.
The assault - which police said was isolated and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
