On Sunday United Nations human rights envoy, Paulo Sergio Pinheiro arrived in Myanmar for the first time in four years when he was denied a visa to the country.

He is here to investigate the abuses carried on in the crackdown in September on democracy protesters, Washington Post reports.

Pinheiro did not address the media upon his arrival in Yangon.

According to U.N. officials in Geneva, Pinheiro has a list of prisons and detention centers he wants to visit in his five-day trip. He is to spend the night in Yangoon and then fly to Naypyidaw, Myanmar’s new capital.

On November 16 he has to hold a news conference in Bangkok after his trip to Myanmar and on December 10-14 he has to report back to the U.N. Human Rights Council.

According to government figures 10 people died in the aftermath of September 26-27, the biggest protest in 20 years. Still the western governments believe that the death toll was higher, closer to 200. Since September more than 3,000 people have been detained and many are still in prison.

The International Commitee of the Red Cross has been denied access to political prisoners in Myanmar prisons for months.

Pinheiro was not permitted to enter the country since November 2003. He said that unless he receives full support from the junta he will abandon his visit to Myanmar.

His visit comes two days after Ibrahim Gambari, U. N. envoy, left Myanmar after succeeding in persuading the junta to allow opposition leader Aung San Suu Kyi to meet with her National League for Democracy colleagues on Friday and hold talks with Aung Kyi.

Suu Kyi declared on Friday after her meetings that she was optimistic about the junta wanting a national reconciliation.

Still great skepticism hovers around the intention of the military junta to share power after ruling Myanmar for the past 45 years.
