Two more people are now in custody related to a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought 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 for suspected conspiring to commit a robbery. They both are still being held, 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 had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT following reports of several people hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
