Police in a small town in Wyoming, US, are trying to trace a man who breaks into houses to log on to porn websites.

According to Associated Press reports, the porn-addict burglar breaks into houses in the town of Gillette and uses the homeowner's PC to buy memberships to porn sites, using stolen cheques from other crimes.

The 'burglar' steals nothing in the raids and the owners only realise there has been a break-in after discovering their computer settings have been changed to automatically log on to the naughty web pages.

One theory is that the burglar has banned from surfing for porn at his own home and is working out his addiction on other people's machines.
