They allege abuse in detention after planning demonstrations in Tiananmen Square against land development officials More than 10 activists were detained on National Day for trying to organise protests in Tiananmen Square against what they claim are corrupt land development officials. Guan Zhenli, a social activist who helps residents fight property developers and urban planning officials, said he and more than 10 others were being held in various Beijing hostels for planning protests that would have involved more than 1,000 people. Some have gone on hunger strike to protest against alleged police abuse while in detention. Most of those who intended to protest had been evicted from their homes recently in Beijing and Shanghai to make way for redevelopment. The residents say they only received partial payment for their properties or too little compensation to buy a new home even on the outskirts of the cities. 'Authorities found out about the protests last week and have held us since Tuesday,' Mr Guan said. 'We've been told not to make trouble during the October 'golden week' period. We were told that we will be held until October 7, when the holidays are over.' Mr Guan made a call to the South China Morning Post on his mobile phone, which officers apparently had not confiscated. 'So far, they're not beating me up yet and they're even feeding me, but they've told me that I can't leave for the coming week. I told them my mother was sick and that I needed go home, but they won't let me go.' He claims one officer threw him against the wall, shouting: 'I'll kill you if you try to leave again.' Mr Guan's temporary arrest - known as rankou or 'soft arrest' - is a common tactic used by police against perceived troublemakers. 'I'm not a troublemaker,' Mr Guan says he shouted at the officer who grabbed him. 'I'm a taxpayer and I have tax receipts to prove it. Where are my taxpayer's rights?' While protests by irate residents forcibly removed from their homes are not usually allowed, officials acknowledge that the nation is experiencing a property bubble and a potential crisis caused by corrupt urban planning officials, bankers and land developers who acquire land at discounted prices and earn kickbacks by inflating the cost of construction projects. Property analysts say it is common on the mainland for land development officials to pay just 30 to 40 per cent of the money they receive from developers to evicted tenants and to pocket the rest. According to Human Rights in China, some of the protesters had travelled from Shanghai to participate in the protest but were arrested on arrival. The rights body added that some detainees had been abused and subjected to 'training sessions' to correct their thinking. 'Residents of Beijing and Shanghai and elsewhere in China are hopping mad about being evicted and paid small amounts of money as compensation,' Mr Guan said. 'Many are now homeless and they can't even vent their anger. Where are our human rights? What kind of a country is the People's Republic of China?'
