It shall be the duty of the chief of police to investigate each location, which is
licensed for consumption on premises periodically. If such investigation reveals that
probable cause for the state's suspension or cancellation of a permit or license exists,
the investigating official shall inform the Texas Alcoholic Beverage Commission immediately
of such fact and furnish supporting evidence. If from such evidence it appears that
cause for a suspension or cancellation exists under the provisions of the Texas Alcoholic
Beverage Code, the chief of police, with any assistance needed from the city attorney,
shall petition the state alcoholic beverage commission to cancel or suspend such permit
or license and shall pursue such petition diligently.
