Two more people are now in custody in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, two women were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers arrested a man in his thirties for suspected robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was isolated and not being treated as an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
