Two more people have been arrested in connection with a theft at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to 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 went to hospital for medical care and have since been discharged.
Officers arrested a 31-year-old man for suspected theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical thought to be an irritant spray.
The attack - which police said was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
