Two more people are now in custody in connection with a theft at Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow 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 after getting out of a car park lift.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for medical care and were later discharged.
Officers detained a man in his thirties for suspected theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be an irritant spray.
The assault - which authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
