An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. Five people went to hospital for treatment and have since been released.
Officers arrested a 31-year-old man for suspected theft and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were called at about 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be an irritant spray.
The attack - an event that police said was isolated and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
