An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both are still being held, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police arrested a 31-year-old man for suspected robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance thought to be pepper spray.
The attack - which authorities stated was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
