Saskatoon police are asking for help from the public in locating letters that could be linked to an ongoing criminal investigation. 

Police said that people and businesses in the Saskatoon area have received packages over the past two months containing letters. Inside the package, there is a request to forward the contents to the address on the envelope. 

Investigators believe the letters are part of an ongoing investigation into harassment, fraud and uttering threats. 

After a lengthy police investigation, Amanda May Totchek, 28, was charged in February. She is scheduled to appear in Saskatoon Provincial Court today on the latest of a total of 50 charges. 

Police discovered a pattern of harassment over the last few years that focused on a Saskatoon man, his friends and acquaintances.

Police ask that anyone in possession of packages or letters of similar nature is asked to contact police at 306-975-8300 or Crime Stopppers at 1-800-222-8477.
