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 an irritant spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the injured during the incident. Five people went to hospital for treatment and have since been discharged.
Police detained a 31-year-old man on suspicion of theft and assault near the location. He has since been released under investigation while inquiries continue.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be pepper spray.
The attack - which police said was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
