The Sun has been forced to block access to a section of its website after a rogue reader took action.

The paper's headline today was 'Pervhunt.com', relating to the publication of details about missing sex offenders on the web.

But the paper failed to secure the rights to the URL and it was bought by a poster from gossip website Popbitch who goes by the moniker of 'onthehushhush'.

Visitors to the pervhunt.com URL were initially transferred to the Child Exploitation and Online Protection Centre site.

But the buyer then mischievously redirected traffic to The Sun's Page 3 Rookies site, where 18 and 19 year-old topless models are shown.

This afternoon The Sun changed the URL on the Rookies page and the URL owner has pointed visitors to another Sun page. The owner has offered to sell the URL to the highest bidder.

Calls to The Sun were unanswered at time of publication.
