Murder detectives are searching for Robert Richard Fraser, also known as Robert Aleem, after 48-year-old Maria Duque-Tunjano was found beaten to death.

Scotland Yard said Fraser is also wanted in connection with an assault on another sex worker, in her twenties, in Paddington on January 18. Officers are warning the public not to approach the Jamaican-born fitness worker, 39, and dial 999. Airports have been put on alert.

Ms Duque-Tunjano, who had rented a room in the townhouse in Earl’s Court Square for four years, was dropped off there by her boyfriend on Tuesday afternoon.
