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 law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was among the those hurt during the incident. Five people were taken to the hospital for treatment and were later released.
Officers detained a 31-year-old man on suspicion of theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT following reports of several people injured by a noxious substance believed to be pepper spray.
The attack - which 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 for a short time.
