Two more people are now in custody in connection with a theft at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals 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 luggage upon exiting 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 treatment and were later discharged.
Police arrested a man in his thirties for suspected robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding several individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
