An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested 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 remain in custody, authorities confirmed.
The arrests follow an investigation into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Police detained a man in his thirties on suspicion of theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of several people hurt by an irritating chemical thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
