An additional two individuals are now in custody related to a theft at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the injured 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 close to the location. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The attack - which police said was a standalone incident and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
