Two more people are now in custody related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and were later discharged.
Officers detained a 31-year-old man for suspected theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding several people injured by a noxious substance believed to be an irritant spray.
The assault - which police said was isolated and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
