Lincolnshire Police are growing increasingly concerned for a missing man from Bourne, who has not been in over a month.
Michael Walker, 54, went missing late in the evening on July 5 this year.
He is about 5ft 10, of a medium build with short grey/brown hair.
Michael was last seen wearing a blue quilted jacket, blue jeans and brown shoes.
His clothing might not seem appropriate for the weather and the force believe he may use bus services to get around.
Anyone who believes they have seen Michael, should contact Lincolnshire Police on 101, quoting incident number 128 of August 4.
