Police are appealing for information regarding the location of Jaroslaw Lichton, 52, from Swindon.
Jaroslaw was last seen at his address in Groundwell Road on 14 January 2018 by a friend but has not returned or made contact with his family since.
He is described as white, 5′ 7″ tall, of skinny build, dark haired with some grey in it and thinning on top.
PC Luke Hobbs said: “It is out of character for Jaroslaw to not have any contact with his family for such a long time and they are understandably concerned for his welfare.
“If you have seen him or have any information on his location please contact us. I would also like to appeal directly to Jaroslaw to come forward and let us know he is safe and well.”
Please call PC Hobbs at Wiltshire Police on 101.
