An additional two individuals are now in custody in connection with a theft at Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases upon exiting a car park lift.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for medical care and were later released.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of a number of individuals injured by a noxious substance believed to be pepper spray.
The attack - which police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
