Two more people are now in custody related to a robbery at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was one of the injured during the incident. A total of five individuals went to hospital for medical care and have since been discharged.
Police arrested a 31-year-old man for suspected robbery and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding several people hurt by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered terrorism - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
