POLICE have turned to Facebook in a bid to trace a missing Wisbech teenager.

Alisa Dmitrijeva, 17, has not been seen since shortly after midnight in Friars Street, King’s Lynn, on August 31.

She was reported missing by a relative on September 6 and now officers are using social media in an effort to help track her down.

They have created a Facebook advert targeted at people living in Wisbech, Norfolk and Lincolnshire.

Users will be directed to a ‘landing page’ on the force website for details of the last sighting of Alisa and the �5,000 reward being offered for information that leads to officers tracing her.

The advert has been created in English, Latvian and Lithuanian.

Det Chief Insp Melanie Dales said: “We know Alisa used social media so this advert will target people who may have information about her whereabouts.

“By translating the advert we hope to reach members of the community who know Alisa but may not have seen the appeals in traditional media.”

Posters, translated into Lithuanian and Latvian, have been handed out by officers in Wisbech, Peterborough, King’s Lynn and Lincoln promoting the reward.

Det Chief Insp Dales also said: “We know Alisa has connections to the Wisbech, King’s Lynn, Peterborough and Lincoln areas and believe that someone knows where she is.

“It’s been several months since anyone saw or heard from her and we are becoming increasingly concerned for her safety.

“I would urge anyone with information about her whereabouts to contact police.”

Anyone with information should contact police on 101 or Crimestoppers, anonymously, on 0800 555 111.
