An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions come after an investigation into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. A total of five individuals went to hospital for treatment and have since been discharged.
Police detained a 31-year-old man for suspected theft and assault close to the location. He has since been released under investigation while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of a number of individuals hurt by a noxious substance thought to be an irritant spray.
The attack - which police said was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
