A Paris appeal court on Thursday upheld a fraud conviction and a fine of hundreds of thousands of euros against the Church of Scientology for fleecing vulnerable followers.

The 2009 conviction saw Scientology's Celebrity Centre and its bookshop in Paris, the two branches of its French operations, ordered to pay 600,000 euros ($790,000) in fines for preying financially on several followers in the 1990s.

The original ruling, while stopping short of banning the group from operating in France, dealt a blow to the movement best known for its Hollywood followers such as Tom Cruise and John Travolta.
