An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers arrested a man in his thirties for suspected theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding several people injured by an irritating chemical thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
