We take the Dyson-Schwinger Equation approach for the quark propagator atcomplex chemical potential for the $N_{f} = 2+1$ QCD. The phase transition linein the imaginary chemical potential region is computed, whose curvature isfound to be consistent with the one at real chemical potential. Moreover, thecomputation in the complex chemical potential plane allows us to determine thelocation of the Lee-Yang edge singularities. We show explicitly that thecritical end point coincides with the Lee Yang edge singularities on the real$\mu_{B}$ axis. We also discuss the possibility of extrapolating the CEP fromthe singularities within a certain range of chemical potential, and investigatethe scaling behavior of the singularities.
