Two more people are now in custody in connection with a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests come after a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for medical care and have since been discharged.
Officers detained a 31-year-old man for suspected theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance thought to be pepper spray.
The assault - which police said was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
