Police have today confirmed that no further action will be taken against two men who were arrested in connection with the death of Alisa Dmitrijeva.

The 17-year-old's remains were discovered on New Year's Day this year on arable land at Anmer, close to Sandringham. She had disappeared from her home in Wisbech in August 2011.

Commenting on the decision, Detective Chief Inspector Jes Fry said: 'All the facts relating to the death of Alisa were submitted to the Crown Prosecution Service for consideration.

'A decision has been made that there is insufficient evidence to prosecute anyone for any offences at this time. Her family have been informed.

'Officers from both Norfolk and Cambridgeshire Constabulary have worked tirelessly, since Alisa's disappearance was reported to us in September 2011, to establish the circumstances surrounding her death.

'This was a complex investigation with many lines of enquiry and I am personally disappointed that we will not be able to offer her family any closure in this case.'

The investigation will remain open and any new information that comes to light will be considered. The matter will now be referred to Norfolk coroner William Armstrong who will set a date for inquest in due course.

Following the discovery by a dog walker at 4pm on 1 January, a DNA profile and palm print later identified the remains as those of Alisa, who was reported missing from Wisbech on September 6, 2011.
