South Yorkshire Police are becoming "increasingly concerned" for the welfare of 62-year-old Charles Dyson who was last seen in Sheffield yesterday morning.
Charles was last seen in the Norton/Woodseats area at 9am yesterday morning and is also known to visit the city centre as well.
He is described by police as around 5ft 7ins tall and of a slim build with short, dark hair with some grey in it and will most likely have facial stubble or a beard.
Charles also has a "misshapen nose" and tattoos on his arms, one of which is a "distinctive black panther".
A statement from South Yorkshire Police read: "Police looking for Charles are becoming increasingly concerned for his welfare and would like to speak to anyone who has seen or heard from him since yesterday morning.
"We believe he may be wearing dark clothing and is often wearing Iron Maiden t-shirts, dark sweatshirts and black work-style trousers with pockets on the side.
"It’s also likely that Charles is wearing black boots or shoes."
Officers added that Charles is not thought to have bruising to his face, explaining the picture was the most recent they had of him.
