Two more people have been arrested related to a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for treatment and have since been discharged.
Police detained a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people hurt by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
