Two more people have been arrested in connection with a theft at London's Heathrow Airport where 21 people 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 for suspected theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people were taken to the hospital for medical care and have since been released.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be pepper spray.
The assault - an event that police said was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
