Two more people are now in custody in connection with a robbery at London's Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. A total of five individuals went to hospital for medical care and were later discharged.
Officers arrested a man in his thirties for suspected robbery and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of several individuals injured by a noxious substance believed to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
