Police have renewed an urgent appeal to trace a Polish man who has been missing from his home for more than 10 days.
Officers say they are increasingly concerned for the welfare of Sebastian Michalak and are urging anyone who spots him to contact them.
The 31-year-old was last seen on the morning of Friday, June 17 in Ochrewell Avenue in Huddersfield.
There have been no sightings of him since and he has not made contact with his family or friends.
Mr Michalak lives and works around Huddersfield and Batley and also has links to Halifax.
He is described as a white male, 6ft tall and of medium build.
He was last seen wearing a cream or white zipped up hoodie with black and white check on the shoulders. He was also wearing black tracksuit bottoms with a white stripe down the side of each leg.
Detective Inspector Ian Mottershaw, of Kirklees CID said: “It is now a week and a half since Sebastian was last seen and we are very concerned for his welfare.
“We need to speak to him as a matter of urgency to check he is safe and well.
“Likewise - if anyone has any information about his whereabouts or thinks they might have seen him then I would urge those people to contact us as soon as possible.
“He left his wallet and personal belongings at home and this disappearance is out of character. His family are also very concerned for Sebastian’s 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 the Adult Safeguarding Unit via 101.
