Two men wielding hammers stormed an Oriental Daily News office in Causeway Bay and injured a staff member yesterday - the third attack against the paper in two days. The pair burst into the ground-floor office in Lee Garden Road shortly after 11am. Two female workers, aged 19 and 36, were ordered to turn round, face the wall and stop talking, said Wan Chai assistant divisional commander (crime), Chief Inspector Lawrence Wong Ying-wai. 'The duo then smashed a glass counter with their hammers, dropped them and fled,' he said. The 36-year-old woman was injured by flying glass and taken to Tang Shiu Kin Hospital. On Thursday, two stolen vehicles rammed into the newspaper's offices in Tsim Sha Tsui and Hunghom in an apparent revenge attack over a report published by the Oriental Daily News' sister paper, The Sun, last week. Threatening notes signed 'Nine Fingers Wah' were found after those attacks.
