Two more people are now in custody related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests follow a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals went to hospital for treatment and have since been released.
Police arrested a man in his thirties on suspicion of robbery and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people injured by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
