An additional two individuals are now in custody related to a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for treatment and were later released.
Police arrested a 31-year-old man for suspected theft and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding a number of individuals injured by an irritating chemical believed to be an irritant spray.
The attack - which police said was isolated and not being treated as terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
