Two more people are now in custody in connection with a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their suitcases 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 treatment and were later discharged.
Police arrested a man in his thirties for suspected robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Police were alerted at approximately 08:10 GMT following reports of several individuals hurt by a noxious substance thought to be pepper spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
