NOT even fraud charges laid against its owner could keep believers away from Guildford's so-called House of Miracles.

Five days a week, George and Lina Tannous throw open their western Sydney home to allow the faithful to witness a mysterious oil-like substance said to seep from their walls.

The family says it is God's work. It started appearing 40 days after the death of their son Mike, 17, in a road accident in September 2006. They believe the oil is his way of communicating with them and, when combined with prayer, has healing powers. The claim brings hundreds of visitors each week to the Bowden Street residence.

But on Wednesday it was the police who visited the House of Miracles and charged Mr Tannous over allegations relating to credit card fraud.
