Two more people have been arrested in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the injured in the event. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Officers detained a 31-year-old man for suspected robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Police were called at about 08:10 GMT following reports of several people hurt by an irritating chemical thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
