An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions follow an investigation into an assault 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 car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for medical care and have since been released.
Officers detained a man in his thirties on suspicion of robbery and assault near the scene. He has since been released under investigation as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding a number of individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
