Two more people are now in custody related to a robbery at London's Heathrow Airport where 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 for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police detained a man in his thirties on suspicion of robbery and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of people injured by a noxious substance believed to be pepper spray.
The attack - an event that authorities stated was isolated and not considered an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
