We present the results of the high-resolution (R$\sim$60,000) spectroscopicanalysis of the star LAMOSTJ045019.27+394758.7 (hereafter J045) from the listof carbon stars of LAMOST DR2. From our analysis, we find that J045 does notexhibit the spectral characteristics of carbon stars. It is found to be ametal-poor ( [Fe/H] = $-$1.05) giant that shows very unusual elementalabundances, particularly for N, Na, V, and Zn. J045 shows ${\alpha}$-elements(Mg, Si, Ca) with near-solar values ($<$[$\alpha$/Fe]$>$ = 0.09) in contrast toGalactic stars that show [$\alpha$/Fe] in the range 0.2 to 0.3 dex. In J045, Scand Ti are under abundant with [X/Fe] $\le$ $-$0.25. Vanadium gives [V/Fe] =0.51 and zinc is under-abundant with [Zn/Fe] = $-$0.62. The object exhibitsnear-solar abundances for Sr, Y, Ba, Pr, and Sm. The La is marginally enhanced,and Ce and Nd are marginally under-abundant in J045. With [Ba/Eu] = $-$0.38,the object falls into the category of neutron-capture rich r-I stars. Theestimated abundances of various elements show that the observed abundancepattern is not compatible with the abundances characteristic of Galacticmetal-poor stars but matches quite closely with the abundance pattern ofSculptor Dwarf galaxy stars of similar metallicity. Based on the aboveobservational evidences, we suggest that the object is a possible SculptorDwarf Galaxy escapee.

LAMOST J045019.27+394758.7, with peculiar abundances of N, Na, V, Zn, is possibly a Sculptor dwarf galaxy escapee
