Two more people are now in custody in connection with a robbery at Heathrow Airport in which 21 people 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 on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals went to hospital for medical care and were later released.
Officers arrested a man in his thirties on suspicion of theft and assault close to the location. He has since been released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT following reports of several people injured by a noxious substance thought to be pepper spray.
The assault - an event that authorities stated was isolated and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
