An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests come after an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and have since been released.
Police detained a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals injured by an irritating chemical thought to be an irritant spray.
The assault - which police said was a standalone incident and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
