Trigonal Cr5Te8, a self-intercalated van der Waals ferromagnet with an out of plane magnetic anisotropy, has long been known to crystallise in centrosymmetric structure. Through detailed structural analysis together second harmonic generation experiments, we show that the compound actually adopts non-centrosymmetric A large anomalous Hall conductivity 102 {\Omega}^(-1) cm^(-1) at low temperature stems from intrinsic origin, which is larger than any previously reported values bulk Cr-Te system. In addition, observe hump-like feature field-dependent resistivity data, resembling typical topological signal. We demonstrate highly tunable and not related effect even though N\'eel-type skyrmions by Lorentz transmission electron microscopy consistent structure compound.
