Two more people are now in custody in connection with a robbery at Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Police detained a man in his thirties for suspected robbery and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of a number of individuals injured by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
