An additional two individuals have been arrested in connection with a theft 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 Lambeth for suspected robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was among the injured during the incident. Five people went to hospital for medical care and have since been discharged.
Police detained a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding several individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that 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.
