An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area 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 follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and were later discharged.
Officers detained a 31-year-old man for suspected theft and assault near the location. He has since been released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance believed to be pepper spray.
The attack - an event that authorities stated was isolated and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
