(Portland, OR) -- A 73-year-old man is recovering from a brutal, unprovoked attack along Portland's Eastbank Esplanade. His family wonders if he was targeted for being Asian. Xinmin Liang  was fishing Tuesday morning near the Steel Bridge, when a white man dressed in gray and a blue beanie approached. Police claim he didn't say a word, just beat the victim with a big wooden stick until it broke and then left. Xinmin has a broken arm and a bruised, swollen face. No arrest has been made. Police are calling this an assault investigation for now, but it could turn into a bias crime.
