An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their suitcases after getting out of a car park lift.
A three-year-old girl was among the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and were later released.
Officers arrested a man in his thirties on suspicion of theft and assault near the location. He has since been released under investigation as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of several people hurt by an irritating chemical believed to be an irritant spray.
The attack - 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 T3 car park for a short time.
