Two more people have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for treatment and were later discharged.
Police arrested a man in his thirties on suspicion of theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people injured by a noxious substance thought to be an irritant spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
