Two more people are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was one of the those hurt in the event. Five people were taken to the hospital for treatment and have since been discharged.
Police detained a 31-year-old man for suspected robbery and assault near the location. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of a number of people injured by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
