Two more people are now in custody related to a theft at London's Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, two women were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt in the event. A total of five individuals went to hospital for treatment and were later discharged.
Police detained a man in his thirties on suspicion of robbery and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of a number of individuals hurt by a noxious substance believed to be an irritant spray.
The attack - which police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
