Two more people are now in custody related to a theft at London's 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 arrested in Lambeth for suspected theft 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 follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, two women were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and were later released.
Officers detained a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical thought to be pepper spray.
The assault - an event that authorities stated was isolated and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
