Two more people are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both are still being held, the force said.
The arrests come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers detained a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance believed to be pepper spray.
The assault - an event that authorities stated was isolated and not considered an act of terror - caused train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
