Officers with the Halton Police Service are seeking the public's assistance in locating a 23-year-old Burlington man.

According to police, Ryan Robichaud left his home on January 15 under unexplained circumstances. He maintained sporadic telephone contact with family members from locations south of the border for some time. However, no one has seen or heard from him since he returned a rented vehicle in Stoughton, Massachusetts on January 21.

Police say his behaviour as of late and his unexplained travel to the U.S. are out of character, causing his family great concern. Police want to make contact with the Burlington resident to ensure his well-being.

Robichaud is white, approximately 5'10" with a thin build. He has short, brown hair and has a beard. He has pierced ears.
