An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for treatment and were later released.
Officers detained a man in his thirties on suspicion of theft and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT following reports of several people injured by a noxious substance thought to be pepper spray.
The attack - which police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
