Two more people are now in custody related to a robbery at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both remain in custody, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their suitcases upon exiting a car park lift.
A three-year-old girl was among the injured in the event. Five people went to hospital for medical care and were later released.
Police detained a 31-year-old man for suspected theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance believed to be an irritant spray.
The attack - which authorities stated was isolated and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
