Two more people are now in custody related to 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 arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
The arrests come after an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for medical care and have since been discharged.
Police detained a 31-year-old man on suspicion of robbery and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of a number of individuals injured by a noxious substance thought to be an irritant 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 main airport tunnel and the Terminal 3 parking facility briefly.
