Two more people are now in custody related to a theft at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers arrested a 31-year-old man for suspected robbery and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of several people injured by a noxious substance thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
