Two more people are now in custody in connection with a theft at Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft 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 come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. A total of five individuals went to hospital for treatment and have since been released.
Police arrested a 31-year-old man for suspected theft and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT following reports of a number of people hurt by an irritating chemical believed to be pepper spray.
The assault - an event that police said was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
