An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, 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 during the incident. Five people were taken to the hospital for treatment and have since been discharged.
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 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance believed to be an irritant spray.
The attack - an event that police said was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
