Police investigating the disappearance of student Richard Okorogheye have found no recent activity on his mobile, a senior officer has said. Detectives are focusing on his phone, as well as his computers and financial activity, and said analysis of the latter has led them to conclude that he took a taxi from west London, where he lives, to the Loughton area of north-east London. The last confirmed sighting of the 19-year-old student, who suffers from sickle cell disease and is considered a high-risk missing person, was captured on CCTV in that area in the early hours of 23 March. On Thursday, officers released the footage as they appealed for anyone with any information to come forward. “There’s a large number of special search officers that are focusing in and around the Epping Forest area, which is close by … but there are other key lines of inquiry that we are still actively pursuing,” said Met police superintendent, Danny Gosling. “In relation to his financial activity, that’s still a valid line of inquiry, and there’s a number of inquiries in and around his laptops, and his computers, which are currently at the laboratory being examined to see whether there’s any other indications, or lines that we can use,” he told reporters on Thursday. Gosling said that, while the searches were still going on, they had yielded no evidence that Okorogheye’s phone has been used recently. He said officers were also working on establishing the truth behind several local reports that the Oxford Brookes University student had been seen at a nearby road junction shortly after the last confirmed sighting. He said: “Our search for Richard is continuing at pace today – we are doing all that we can to locate him and bring him home to his family, who miss him dearly. “Officers have been working tirelessly behind the scenes in an effort to trace Richard’s movements that evening, with assistance from specialist search teams, the Met’s dog and mounted branch units and colleagues from other police forces.” Okorogheye left his family home in Ladbroke Grove on the evening of Monday 22 March and was reported missing two days later. After initial inquiries, he was identified as having left his home address and heading in the direction of Ladbroke Grove at about 8.30pm. He was seen boarding the 23 bus southbound in Ladbroke Grove at 8.44pm. Police said he then took a taxi from the W2 area of London to a residential street in Loughton, in Essex. CCTV footage showed him walking alone on Smarts Lane towards Epping Forest at 12.39am on Tuesday 23 March. His mother has told reporters she believes he may have been going to meet someone he had been talking to online. Gosling said: “At this stage, we don’t know why Richard has come to Loughton, there is no clear reason.”
