Police are seeking help in finding the wherabouts of Anna Mejlun, a 22-year-old who has gone missing from her home in Louth.
Anna is a Polish national, who has been living and working in Louth, together with her brother.
Police say Anna travelled out of the county on Friday May 24, possibly to Cumbria to meet someone she had met on the internet. She phoned her brother the following day and was due to return home and return to work soon after.
Police say Anna did not return and has made no contact with her family since. She was reported missing to Lincolnshire Police on June 24 and enquiries are ongoing with police colleagues in Cumbria and Lanarkshire as efforts are made to find Anna and ensure she is safe and well.
Anyone with information should contact PC Andy Spencer at Lincolnshire Police by calling 101.
