Two more people are now in custody in connection with a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to police.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. A total of five individuals went to hospital for treatment and have since been discharged.
Police detained a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several people injured by a noxious substance believed to be pepper spray.
The assault - an event that police said was isolated and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
