Interpreters are standing by as police appeal to members of the Eastern European community for information about the last movements of murdered student Alisa Dmitrijeva, whose remains were found on the Royal Estate in Norfolk on New Year's Day.

Detectives sealed off a remote copse near the Royal Stud after human remains were found by a dog walker on New Year's Day.

DNA taken from the body confirmed it was that of Latvian-born Alisa, 17, who was reported missing from her home in Wisbech on September 6.

Today Det Chief Insp Jes Fry, who is leading the investigation into the case, said: 'Now that we have identified Alisa, we can carry out more focused inquiries to establish what happened to her.

'We particularly want to speak to anyone who may have seen Alisa between midday on Tuesday, August 30; and midnight on Tuesday, September 6.

'We know she was in both the King's Lynn and Wisbech areas during this time, and want to hear from anyone who has any information about her whereabouts over these eight days.

'We particularly want to speak to people within the Latvian, Lithuanian and Russian communities in these areas, and are working with local groups and individuals who may be able to assist.

'We have access to a language line and interpreters who can help anyone calling in with information to Norfolk Constabulary.'

Police have already spoken to a number of members of Royal staff, including grooms and a gamekeeper.

Alisa's remains were found just over a mile from sandringham House, where the Queen, Duke of Edinburgh and other members of the Royal family spent Christmas.

DCI Fry added: 'We are also still keen to speak to anyone who was working in the Anmer area, specifically between August 30 and September 6, and anyone who held or was involved in organising any kind of function at Sandringham or neighbouring parishes during that time.'

Anyone with any information relating to the incident should contact the Joint Norfolk and Suffolk Major Investigation Team at Norfolk Constabulary on 101 or Crimestoppers anonymously on 0800 555 111.
