A gang of hoodies mugged a teenager as he was walking his dog.
The 15-year-old boy was in Community Park, Lewknor, last Sunday at about 6.15pm.
A gang of six youths, all wearing hooded tops, demanded he emptied his pockets than stole his keys.
Pc Mark Riding said: "This is an area that is very rural and we think local people may have information about these youths.
"The young boy targeted has been left shaken up and we are hoping that we can clear this incident up quickly."
Anyone with information should contact police on 08458 505505 or anonymously to Crimestoppers on 0800 555 111.
