23-year-old Minod Monger left his home in Ecclesfield at around 5.30pm on Monday, June 10, wearing a white bomber jacket, great tracksuit bottoms and black crocs.
Police say he may have been seen near Wooley Wood Bottom on Thursday, June 13, between 12.45pm and 1.15pm, but since then there have been no further sightings.
Now, Minod’s parents and South Yorkshire Police have appealed for people’s help in finding their son and bringing him home.
They said: “Please help us find out son. It is not like Minod to be away from home for such a long time without being in touch.
“The weather is going to get worse this evening and we need to make sure he is safe.
“If you see Minod please do not approach him as it is likely he will run away or get distressed as he is not used to being around new people.
“Please call 999 and let police know where he is and they can make sure he is looked after.
“Minod, is you see or hear this you are not in trouble, we love you and want to make sure you are ok. Please get in touch.”
Officers say they would like to speak to anyone who may have seen a man matching Minod’s description or drove along the road between these times and may have captured their drive on dashcam footage.
If you have seen Minod or know know where he might be please call South Yorkshire Police on 101 quoting incident 715 of 10 June.
