U.N. peacekeepers called Thursday for a renewed police investigation into the disappearance of a Haitian human rights activist and senate candidate who was reported missing more than two months ago.

Since his abrupt disappearance, scant information has emerged about Lovinsky Pierre-Antoine, a high-profile activist and member of ousted President Jean-Bertrand Aristide's Fanmi Lavalas party.

The U.N. mission is "concerned to note that we have still not received news about a person of stature, a political activist, who disappeared two months ago," said spokesman Mamadou Bah. He added that Haitian police have not responded to U.N. offers to assist with the investigation.

Police spokesman Frantz Lerebours said there was no new information on Pierre-Antoine, and would not provide further details.

Pierre-Antoine, a leader of the pro-Aristide September 30 Foundation and critic of both U.N. and U.S. involvement in Haiti, was last seen leaving his Port-au-Prince home shortly before midnight Aug. 12, said Ronald Saint-Jean, leader of a coalition called the Group Initiative to Save Lovinsky Pierre-Antoine.

Saint-Jean and other supporters say Pierre-Antoine had received threats because of his ties to Aristide, and they believe he was abducted because a rented SUV he was using at the time was found abandoned outside his home.

No ransom note was ever issued, Saint-Jean said. "We are putting pressure on the authorities to give us an answer," he said.
