Base on about 4,500 large tangential velocity($V_\mathrm{tan}>0.75V_\mathrm{esc}$) with high-precision proper motions and$5\sigma$ parallaxes in Gaia DR2 5D information derived from parallax andproper motion, we identify more than 600 high velocity stars with $50\%$unbound probability. Of these, 28 nearby (less than 6 kpc) late-typeHypervelocity stars (HVSs) with over $99\%$ possibility of unbound arediscovered. In order to search for the unbound stars from the full Gaia DR2 6Dphase space information derived from parallax, proper motion and radialvelocity, we also identify 28 stars from the total velocity($V_\mathrm{gc}>0.75V_\mathrm{esc}$) that have probabilities greater than$50\%$ of being unbound from the Galaxy. Of these, only three have a nearly$99\%$ probabilities of being unbound. On the whole HVSs subsample, there is 12sources reported by other surveys. We study the spatial distribution of angularpositions and angular separation of HVSs. We find the unbound HVSs arespatially anisotropic that is most significant in the Galactic longitude atmore than $3\sigma$ level, and lower unbound probability HVSs aresystematically more isotropic. The spatial distribution can reflect the originof HVSs and we discuss the possible origin link with the anisotropy.
