ADDIS ABABA - Ethiopian police have arrested a blogger who criticized the government, especially its handling of the ongoing protests in the Oromia and Amhara regions.

Seyoum Teshome, an outspoken university lecturer who has been quoted frequently by international media about the anti-government protests, was detained Oct. 1 at his home in Wolisso town in the Oromia region.

Ethiopia's government spokesman, Getachew Reda, told The Associated Press on Tuesday that he heard about Seyoum's arrest and is investigating the reasons why.

Days before his arrest, Seyoum told the AP that he was planning to start his doctoral studies at Addis Ababa University and was starting his own blogging website, Ethiothinkthank. He wrote about Ethiopia's anti-government protests on his blogging site and Facebook page.

"This arrest of a prominent writer and commentator is deeply disturbing as it comes against a backdrop of government moves to stifle protests and criticism," said Robert Mahoney, deputy director of the New York-based Committee to Protect Journalists. "Seyoum Teshome should be released without delay and without condition."

Ethiopia is the third worst jailer of journalists in Africa, and a number of journalists are serving jail terms for writing critical pieces about the government, said the journalists' group.

The arrest came a day before dozens of people were killed in the Oromia region. They were crushed in a stampede after government forces fired tear gas and bullets to disperse angry protesters during the annual Irrecha thanksgiving celebration of the Oromo people. The government has said 55 have died, but online activists and opposition groups outside Ethiopia claim the death toll is much higher.

The incident has sparked renewed protests in many towns across Oromia, where over the past year anti-government protests have called for respect for human rights, wider freedoms and the release of detained opposition figures and journalists.
