An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed 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 robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both are still being held, the force said.
These detentions follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was one of the injured during the incident. Five people went to hospital for medical care and have since been discharged.
Officers detained a man in his thirties for suspected robbery and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be an irritant spray.
The assault - an event that police said was isolated and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
