A former factory in Radford is being searched in the hunt for the body of Bogdan Nawrocki.
Detectives are searching a building in Russell View as part of the ongoing investigation into the disappearance of the 22-year-old earlier this year.
Bogdan, who was from Poland, but living close to his sister in Radford, has not been seen since Sunday, January 5.
One man has been charged with his murder and three others remain on bail pending further enquiries.
Last month one suspect was re-arrested for murder but was later re-bailed.
Detective Chief Inspector Tony Heydon is leading the inquiry. He said: "As we continue to receive intelligence we will continue to pursue these new lines of enquiry. We believe Bogdan has been murdered and our aim now is to find his body and give his family the justice they deserve.
"Bogdan's sister Monica is being supported by police and kept updated with developments – she deserves to know what has happened to her brother.
"If you have information that could help us locate Bogdan's body then please pick up the phone. Your call will be treated with the utmost confidence. "
Anyone with information should contact the incident room on 0115 8446913 or Crimestoppers anonymously on 0800 555 111. A dedicated line manned by Polish-speaking officers has also been set up on 07785 573415.
