An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth 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 follow 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 upon exiting a car park lift.
A three-year-old girl was one of the those hurt during the incident. Five people went to hospital for medical care and have since been released.
Officers detained a man in his thirties on suspicion of robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding several people hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
