An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests come after a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt in the event. Five people were taken to the hospital for medical care and have since been discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of a number of individuals injured by a noxious substance thought to be pepper spray.
The assault - which police said was isolated and not considered terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
