An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by police.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police arrested a man in his thirties on suspicion of robbery and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
