We show that there is a low metallicity tidal stream that runs along l = 143 ^ { \circ } in the South Galactic Cap , about 34 kpc from the Sun , discovered from SEGUE stellar velocities .
Since the most concentrated detections are in the Cetus constellation , and the orbital path is nearly polar , we name it the Cetus Polar Stream ( CPS ) .
Although it is spatially coincident with the Sgr dwarf trailing tidal tail at b = -70 ^ { \circ } , the metallicities ( [ Fe/H ] = -2.1 ) , ratio of blue straggler to blue horizontal branch stars , and velocities of the CPS stars differ from Sgr .
Some CPS stars may contaminate previous samples of Sgr dwarf tidal debris .
The unusual globular cluster NGC 5824 is located along an orbit fit to the CPS , with the correct radial velocity .
