The family of a Queensbury man who vanished over a month ago are appealing for help to find him as detectives in Calderdale issued new CCTV images.
Mr Alderson, aged 44, who is originally from the Queensbury area, was last seen on Friday January 20 and has not been in touch with any friends or family.
Craig’s sister, Mandy Sladen, said: “Craig has been missing for well over a month now and the whole family are incredibly worried. We are appealing to Craig to contact anyone, friend or family, just to let us know he’s safe.
“We are hoping that these new images of him from Queensbury, where he was last seen, will help anyone out there who has that missing piece of information we need.
“The police have continually been in touch with us since Craig went missing and we are pleading to anyone who knows anything about his disappearance to urgently get in touch with the police to help find him.”
The CCTV images are from Chapel Street, in Queensbury on January 20 around 10.45pm, which shows Craig holding a laser measuring device in his hand.
Officers in Calderdale have been conducting extensive enquiries to locate Craig, both in residential areas and open ground, working alongside local Search and Rescue teams and partners across both Bradford and Calderdale districts.
They have also been continually in touch with Craig’s family, friends and acquaintances.
Detective Chief Inspector Chris Gibson, of Calderdale Police said: “We hope that releasing these new images and video of Craig that they might jog someone’s memory and members of the public can assist us in trying to trace him.
“It is extremely out of character for Craig to go missing and for him not to be in contact with his friends and family. We have been conducting extensive enquiries for the last month to locate him.
“I firmly believe that the answers to finding Craig lay within the Queensbury area, and once again to appeal to anyone who thinks they may have seen him, or anyone who has heard from him or knows where he is now to get in contact with the police.
“We are ever increasingly concerned for Craig’s welfare and our investigation is ongoing as we continue to strongly urge anyone who has any information to come forward as soon as possible.”
Any information about Craig’s whereabouts should be passed to police by calling 101 and quoting 13170034270.
