Two more people are now in custody in connection with a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people were taken to the hospital for treatment and have since been released.
Officers arrested a man in his thirties on suspicion of theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of several individuals injured by a noxious substance thought to be an irritant 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 briefly.
