An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for treatment and have since been discharged.
Officers detained a 31-year-old man for suspected theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding several people hurt by a noxious substance believed to be an irritant spray.
The assault - which police said was isolated and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
