Two more people are now in custody related to a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. A total of five individuals went to hospital for treatment and have since been released.
Police detained a man in his thirties on suspicion of robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Police were called at about 08:10 GMT after reports came in regarding several people injured by an irritating chemical believed to be pepper spray.
The assault - which authorities stated was isolated and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
