By George Thande VICTORIA, Oct 4 (Reuters) - Seychelles President James Michel accused the opposition on Wednesday of irresponsibility after a rare outbreak of unrest in the Indian Ocean archipelago. Police used teargas on Tuesday to disperse scores of opposition supporters who were outside parliament protesting against a ban on political or religious groups running radio stations. The leader of the opposition Seychelles National Party (SNP), Wavel Ramkalawan, was among four people injured, while a newspaper editor was also arrested. "Stability and peace are very important but we have a very irresponsible opposition with members who have no respect for the rule of law even though some of the instigators are actually lawmakers," President James Michel told journalists, soon after returning from a European visit. Ramkalawan, an Anglican priest, was due to be released from Victoria hospital later on Wednesday, officials said. SNP secretary-general Roger Mancienne, who is also the editor of the opposition Regar weekly, was arrested and released on bail, Police Commissioner Gerard Waye-Hive told Reuters. On Wednesday, workmen were busy repairing smashed shop windows close to the scene of the melee on the biggest of the archipelago's 115 islands. The protests erupted after parliament passed an amendment on Tuesday prohibiting any political or religious organisations from getting a licence to run a radio station. In July, Michel led his ruling Seychelles People's Progressive Front (SPPF) to win a closely fought poll against Ramkalawan's SNP party. The SPPF has ruled since 1977. Independent newspapers in the Seychelles do exist and are critical of officials -- but government dominance of most media and the threat of libel suits restrict freedom, critics charge. "President James Michel's government must admit that it is high time it peacefully relinquished its grip over news and information in Seychelles. And there was absolutely no valid reason for arresting Mancienne," Paris-based Reporters Without Borders said in a statement about the unrest.
