Call him Hack-ula.

Police are seeking the public’s help in nailing a gunman who repeatedly sank his teeth into a livery cab driver in an attempted robbery in The Bronx.

Driver Mouhamodou Seck, 52, suffered at least five bite marks to his back, arms and neck during the toothy town-car tussle early Thursday, cops said.

“All from his teeth! All them is teeth!” Seck told WABC.

Seck told cops the bloodthirsty monster hailed him on East 130th Street at Lexington Avenue in Manhattan and asked to be driven to West 180th Street in University Heights.

Instead of paying upon reaching his destination, the fiendish freak brandished a gun — then struck with his molars.
