Two more people are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the those hurt during the incident. Five people were taken to the hospital for medical care and were later discharged.
Police arrested a man in his thirties for suspected robbery and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of several people injured by a noxious substance believed to be pepper spray.
The assault - which police said was isolated and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
