Two more people have been arrested in connection with a theft at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft 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 an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for medical care and were later discharged.
Police arrested a man in his thirties for suspected theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was a standalone incident and not considered terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
