A man may have frozen to death after going missing in woodland, police fear.
The man's body was found on Thursday night after four friends went into Newmarket police station in Suffolk reporting that he had not been seen for four days.
The men had been searching for him and found him dead in a wooded area. He had not previously been reported as missing to police.
Officers visited the scene and found the body of the man, aged in his 30s or 40s.
A spokeswoman said: "The area has been cordoned off while an initial investigation gets under way at the scene."
The death is being treated as unexplained but one theory is that he died in the freezing temperatures.
Anyone with information is asked to call Suffolk Police on 101.
