An additional two individuals have been arrested related to a theft at London's Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for treatment and were later released.
Police arrested a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were called at about 8:10 in the morning GMT following reports of a number of individuals hurt by an irritating chemical thought to be an irritant spray.
The assault - which police said was isolated and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
