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, according to police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people were taken to the hospital for medical care and were later released.
Police detained a 31-year-old man on suspicion of theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 08:10 GMT following reports of a number of individuals hurt by a noxious substance believed to be an irritant spray.
The attack - an event that police said was isolated and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
