Two more people have been arrested in connection with a theft at London's Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt in the event. Five people went to hospital for treatment and were later released.
Officers arrested a man in his thirties for suspected theft and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical thought to be pepper spray.
The attack - which police said was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
