Two more people have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for treatment and have since been discharged.
Officers detained a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released under investigation as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of a number of individuals hurt by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
