(Yahoo News) - “Bala! Bala!” The crowd cheered as private investigator P Balasubramaniam walked with his hands raised into a packed hall at the Kuala Lumpur and Selangor Chinese Assembly Hall (KLSCAH). And thus the night began with an air of anticipation – that something "big" will be revealed.

Hundreds of people poured into the hall last night while others watched on a screen provided outside despite the rain yesterday evening.

Close to 1,000 people from all walks of life -- from a young man with skinny jeans and eyeliner to elderly grandfather wearing a kopiah -- anxiously waited for the main event.

The night began like a concert with opening acts to warm up the audience. Controversial political cartoonist Zulkiflee Anwar Ulhaque or Zunar and Suaram director Cynthia Gabriel took to the stage to fire up the crowd and set the backdrop for Bala’s "revelations".

After more than an hour, Bala finally took the stage and sat with Solidariti Anak Muda Malaysia (SAMM) chief Badrul Hisham Shaharin, who was the moderator.

Bala, who had just returned home on Sunday, Feb 24, after being in hiding since 2008, was now centre stage, looking visibly nervous. He started his two-hour-long "talk" by recounting how he met Abdul Razak Baginda to the day he issued his second statutory declaration (SD).

Bala, the key witness in the Altantuya Shaariibuu murder trial, had linked the then deputy prime minister Najib Razak to the murder in his first SD. However, he retracted the passage regarding Najib in the second SD the next day. - See more at: http://fz.com/content/pi-bala-back-arrives-klia-heros-welcome

Bala was the key witness in the Altantuya Shaariibuu murder trial, and he had linked the then deputy prime minister Datuk Seri Najib Razak to the murder in his first SD. However, he retracted the passage regarding Najib in a second SD the next day.

Bala stumbled on his words, constantly referring to PowerPoint slides to help remember the events, and it went on for so long that he even took a toilet break. “I am very sorry. I haven’t been in the country for so many years so I hope you will have patience with me,” he apologised to the crowd.

Although Bala repeated and revealed nothing new, the audience were at the edge of their seats, glued to his words. The crowd cheered and jeered every time Bala mentioned the names of the prime minister and his wife.

Bala also gave his version of what happened when he met businessman Deepak Jaikishan after he issued his first SD.

“We went to one Chinese shop in Rawang and he (Deepak) was asking what do you get by doing that SD one? Then suddenly I received a call from my wife that she getting harassed by two Malay men outside the house... He (Deepak) said 'don’t worry. If you can prepare this SD then everything will be solved'.

Bala also claimed that he had allegedly met Datuk Nazim Razak at The Curve and that Nazim had threatened Bala's family because of the first SD.

Badrul later promised that last night was the first of many public forums that SAMM planned to organise with Bala nationwide, promising to drop more “bombs” in Kelantan, Johor and Sabah.

Bala declined to speak to reporters.
