Two more people have been arrested in connection with a theft at London's Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
The arrests come after a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, two women were robbed of 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 medical care and have since been discharged.
Officers arrested a man in his thirties on suspicion of theft and assault near the location. He was subsequently released under investigation while inquiries continue.
Authorities were called 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 assault - which authorities stated was isolated and not being treated as an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
