An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was among the those hurt in the event. A total of five individuals went to hospital for treatment and were later discharged.
Police arrested a 31-year-old man for suspected robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 parking facility briefly.
