Police say they are growing increasingly concerned for the welfare of a 31-year-old Polish man who has gone missing from his home in Huddersfield.
Sebastian Michalak was last seen on the morning of Friday, June 17, in Ochrewell Avenue, Deighton.
He has not been seen since then and has not made any contact with his family or friends.
He is described as white, 6ft and medium build. He lives and works in the Huddersfield and Batley area.
Det Insp Mark Colman, of Kirklees CID said: “Sebastian has left his wallet and personal belongings at home and has not been heard from for a number of days.
“This is out of character for Sebastian and his family and police are concerned for his welfare.
“We would ask anyone who has seen Sebastian or with information about his whereabouts to please contact the police.
“Similarly, we would ask Sebastian himself to make contact either with the police or his family to confirm that he is safe and well.”
Anyone with information is asked to contact Kirklees CID or Adult Safeguarding Unit via 101.
