DALLAS -- Dallas say the department shut down its Internet presence after a hacker took over its Web site and filled it with anti-American rants.

The vandalized Web pages included a doctored photograph showing American troops watching over four people lined up against a wall.

Each of the four prisoners had lines leading away from their faces to individual head shots of President George W. Bush, Vice President Dick Cheney, Secretary of State Condoleezza Rice and Sen. John McCain

Dallas police spokesman Vernon Hale said no internal police data was affected.

The Web site was taken down indefinitely while the police technology unit investigates.
