Two more people are now in custody in connection with a theft at London's Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases upon exiting a car park lift.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals went to hospital for treatment and have since been discharged.
Police arrested a man in his thirties for suspected theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT following reports of a number of people injured by a noxious substance thought to be an irritant spray.
The assault - an event that police said was isolated and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
