An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, 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. Both individuals are still being held, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police 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 about 8:10 in the morning GMT after reports came in regarding a number of individuals injured by an irritating chemical believed to be an irritant spray.
The assault - an event that police said was isolated and not considered terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
