An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests follow 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 among the those hurt in the event. Five people went to hospital for treatment and were later discharged.
Police detained a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of several individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was isolated and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
