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 man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals were taken to the 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 alerted at about 08:10 GMT following reports of several individuals injured by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
