Caracas, Venezuela ? Thousands of angry government opponents chanting “This is a dictatorship!” rallied in the capital’s streets Thursday, protesting the midnight arrest of a strike leader by secret police.

But President Hugo Chavez triumphantly proclaimed that he authorized the arrest of Carlos Fernandez even though it threatened to re-ignite protests and paralyze the country.

“One of the coup plotters was arrested last night. It was about time, and see how the others are running to hide,” Chavez said at the foreign ministry. “I went to bed with a smile.”

Chavez said judges should not “be afraid to issue arrest warrants against coup-plotters.”

Fernandez, head of Venezuela’s largest business federation — Fedecamaras, was seized by about eight armed agents around midnight Wednesday as he left a restaurant in Caracas’ trendy Las Mercedes district, said his bodyguard, Juan Carlos Fernandez.

The men fired into the air when patrons tried to prevent the arrest, the bodyguard said.

Fernandez faces charges of treason and instigating violence for leading the two-month strike that began Dec. 2, seeking to oust Chavez and force early elections.

The strike ended Feb. 4 in all sectors except the critical oil industry. Before the strike, Venezuela was the world’s fifth-largest petroleum exporter and a major U.S. supplier.

Government allies warned that more than 100 opposition leaders, from labor bosses to news media executives, who supported the strike also could be arrested.

“More than one hundred are on the list to be captured,” ruling party lawmaker Luis Velasquez said.

The existence of such a list could not be immediately confirmed.

Opposition sympathizers at Thursday’s rally near an air force base in eastern Caracas lambasted Chavez, accusing the leftist leader of trying to establish a Cuban-style dictatorship in this South American nation of 24 million people.

“This is an escalation of violence by the government, which has arrived at the extreme of repression,” said Carlos Feijoo, 88, a retired oil worker.

Fedecamaras vice president Albis Munoz warned of another nationwide strike in response to the arrest.
