An additional two individuals are now in custody related to a theft at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, according to law enforcement.
A man, 24, 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. They both remain in custody, the force said.
These detentions follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. Five people were taken to the hospital for medical care and were later released.
Officers arrested a man in his thirties on suspicion of theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by an irritating chemical thought to be pepper spray.
The attack - an event that authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
