An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their suitcases after getting out of a car park lift.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers arrested a man in his thirties for suspected robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by an irritating chemical believed to be pepper spray.
The attack - an event that police said was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
