Two more people have been arrested related to a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, according to police.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests follow an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals went to hospital for treatment and have since been discharged.
Officers detained a man in his thirties for suspected theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of a number of people hurt by an irritating chemical believed to be pepper spray.
The attack - which authorities stated was isolated and not being treated as terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
