An axe-wielding man tried to force his way into a police barracks last week in the northeastern province of Liaoning - the third publicised case of an attack at a PLA camp within a week, local official and state media said yesterday. The armed man was wrestled to the ground by Song Yaoqi, a sentry stationed outside the PLA Armed Police Force Division in Shenyang, Liaoning's capital. No one was injured, the People's Armed Police Force newspaper reported. A spokesman for the information office of the Shenyang division confirmed that the incident took place around 9pm on March 24, but refused to give details. The weekly newspaper said Mr Song had been alerted by a man who showed an awkward bulge in his jacket and glanced right and left while walking towards the gate of the barracks. As soon as the man was stopped by Mr Song outside the gate, he suddenly took an axe from his jacket and shouted, 'Get away from me! I will kill anyone who tries to stop me,' the report said. But Mr Song was calm and quickly activated an alarm behind him to seek help. He then took away the man's axe and wrestled him to the ground. The report failed to give the axe-wielder's name or his motivation for wanting to break into the barracks but reported that local police took him into custody. Violent attacks targeting military personnel have been rare, but such cases have increased in the past month. On March 19, a sentry of a PLA Chongqing division was shot dead at close range by a mysterious attacker, raising public fears over relaxing security in military barracks. Police are still hunting the suspects. On March 26, a PLA sentry in Leshan, Sichuan, who was in the same division as the victim of the Chongqing attack, was assaulted by a man with a dagger. The sentry was injured and the attacker was still at large last night. The Yibin Public Security Bureau in Sichuan announced it had arrested four suspects who were involved in four attacks in the city in the past six years, China National Radio said yesterday. It said all the four strikes were carried out by the same criminal gang. The gang had attacked a satellite observation station and a municipal governmental security office in 2003 and robbed two highway toll booths in the city last year and this year. In Urumqi, Xinjiang, a traffic policeman was attacked by a passer-by who was trying to cross a highway on Monday night, Xinhua said. It said three policemen saw the passer-by stroll along the highway while they were taking a suspect into custody. The three said they stopped him to prevent a traffic accident. One officer hit by a brick sustained a fractured skull.
