An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was among the those hurt in the event. A total of five individuals went to hospital for medical care and were later released.
Officers detained a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released under investigation while inquiries continue.
Police were alerted at about 8:10 in the morning GMT following reports of several people hurt by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - 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.
