An anonymous trail setter has hidden painted stones in the forest.

The person, who contacted the Guardian Series under the name of J R, claimed to have found two pebbles while out cycling.

One bore a small, illegible inscription, the other a pink pig sniffing a flower.

The person has refused to say where the stone were found, but has urged walkers to keep their eyes peeled when waling through Epping Forest for more mysterious rocks.
