Two more people are now in custody in connection with a robbery at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman 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-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt in the event. Five people were taken to the hospital for medical care and were later discharged.
Police detained a man in his thirties for suspected robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of several people injured by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
