Detectives hunting the killer of a Latvian land worker in Lincoln have praised residents for their help.
Detective Superintendent Stuart Morrison, who is leading the murder investigation, has been pleased by the amount of help the city's migrant population has given his team.
Vasilijs Ransevs, 33, was found dead in his Portland Street flat on June 16. And Det Supt Morrison said he is delighted with the response to the request for voluntary fingerprints and DNA samples from neighbours.
"We have had a high level of co-operation from the local people, they have been very helpful," he said.
"Having local language officers down there helps because people are understanding what we are doing and why we are doing it.
"We are talking to witnesses and we are finding out more about Mr Ransevs as a man and how he lived his life."
Police have traced Mr Ransevs's partner in his native Latvia and are planning to fly her to England this weekend.
They had previously contacted his mother in Latvia and a sister in Ukraine.
"We have made more contact with his family by phone," added Det Supt Morrison.
"We have got plans to bring his partner to the country this weekend, but his mother is not well enough to travel.
"We need more information about him which we can get from his partner and face to face conversations are more effective than over a mobile phone with a translator."
Tests are still ongoing to determine the exact nature of the head injury that killed Mr Ransevs and the results may not be known for a while.
