Two more people are now in custody related to a robbery at London's Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for treatment and have since been released.
Officers detained a man in his thirties on suspicion of robbery and assault near the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance believed to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
