An additional two individuals are now in custody related to a robbery at Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. Five people were taken to the hospital for treatment and were later released.
Officers detained a 31-year-old man on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of a number of people hurt by a noxious substance thought to be pepper spray.
The assault - which authorities stated was isolated and not being treated as terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
