Derbyshire Police are concerned for the safety of a 67-year old man who went missing from his Chesterfield home.
Michael Peach left his home in Cuttholme Road, Chesterfield, on Sunday 11th May at around 10am.
He was due to attend a fishing match at either Holmebrook Valley Park or Linacre Reservoirs, but didn't turn up at those locations.
Mr Peach is white, with grey hair, of slim build, and was wearing a blue Parker coat with a hood, grey tracksuit bottoms and trainers.
Police say he is a keen walker known to walk long distances.
Anyone with information on his whereabouts, or who might have seen him since 10am yesterday, should call police immediately on 101.
