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 police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and have since been released.
Police arrested a man in his thirties for suspected robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
