Two more people have been arrested in connection with a theft at London's Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals went to hospital for medical care and were later discharged.
Police arrested a man in his thirties for suspected theft and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT following reports of a number of people injured by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
