Police investigating the disappearance of a 20-year-old man after he visited a nightclub in central London last week have begun searching the River Thames after reviewing CCTV footage. Scotland Yard said the search for Harvey Parker was ordered after officers found footage suggesting he may have “entered the water” near the Golden Jubilee pedestrian bridge that links Embankment to Waterloo. In a statement, it added: “At this stage of the investigation there is nothing to suggest that there is any third-party involvement.” Parker, from Lambeth in south London, was seen leaving Heaven Nightclub alone near Charing Cross Railway Station in Westminster at about 2.15am last Friday. DCI Lucy O’Connor, of the central south safeguarding unit, said: “We are doing all we can to find Harvey, and working closely with our colleagues in the marine policing unit.” She added: “We are keeping Harvey’s family fully informed of any developments; and the thoughts of my colleagues and I are with them at this distressing time. We would also ask that media avoid any speculation while the inquiry continues.” On Tuesday police released CCTV images of Parker after he left the nightclub. They showed him then entering Craven Street and walking south towards the Embankment. He has not been seen since. DS Dick Nation, also of the central south safeguarding unit, said: “This is a terrible ordeal for Harvey’s family and friends and I would urge anyone who saw him or has any information to contact police immediately.” The Theatre Royal Stratford East tweeted that Parker was a front-of-house member of staff and issued an appeal for help to find him. A friend said the University of York music student had been to a Little Simz concert in Brixton, south London, before going on to Heaven nightclub. Parker’s relatives have also taken to social media to ask for help in locating him.
