An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A three-year-old girl was one of the injured during the incident. Five people went to hospital for treatment and have since been released.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The assault - an event that police said was a standalone incident and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
