An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, two women were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals went to hospital for medical care and have since been discharged.
Officers detained a 31-year-old man on suspicion of robbery and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance believed to be pepper spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
