Concern is growing for a teenager from Oldham who went missing more than a month ago.
Ciaron Nuttall, 19, was last seen on Cardigan Street, Royton, on 5 March.
Greater Manchester Police said he had not used his mobile phone or used his social network account since, and he had not accessed his bank account.
Officers from the major incident team were in Royton on Thursday delivering leaflets to local residents appealing for information.
Mr Nuttall is white, 5ft 9in (1.7m) and slim with short brown hair.
The former barman at the Railway Pub in Royton was well known locally, police said.
He has links to Oldham and Rochdale and family members in Wigan.
Police said Mr Nuttall had been with a friend at 1000 GMT on 5 March.
He sent a text message at 1300 GMT, from the Royton area. The phone then switched itself off, as it had run out of power, on 13 March.
Det Ch Insp Pete Giles said: "We have carried out extensive inquiries to try to find Ciaron but we are not really any closer to knowing where he may have been since he was last seen in Royton last month.
"We really need the public's help to find him as his family are understandably very worried, as are we.
"If anyone has seen or spoken to Ciaron or perhaps put a roof over his head at any time over the last month please call us.
"I also want to urge Ciaron himself to make contact and must stress that whatever worries you have, they can be resolved.
"Your family and the police just want to know that you are OK."
