An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit 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 this past Sunday. Before the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt in the event. Five people were taken to the hospital for medical care and have since been discharged.
Officers arrested a 31-year-old man for suspected robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were called at about 08:10 GMT following reports of a number of individuals injured by an irritating chemical thought to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
