At a news briefing Tuesday, Marks told reporters that they would be hearing from him on issues such as corruption in high places, overseas properties and bank accounts, drug trafficking and money laundering, the drug-related murder of Herman Sanichar, the back-track related murder of Lloyd Bacchus, and the murder of a Customs officer at Grove on the East Bank Demerara.

The Sanichar and Bacchus murders took place several years ago.

Marks has claimed that there is a conspiracy by members of the Guyana Revenue Authority, politicians and "corrupt businessmen" to "damage" or "get rid" of him because of his actions to nab tax evaders.

But Commissioner General of the Guyana Revenue Authority, Mr. Edgar Heyligar, yesterday refuted charges by Marks that he (Heyligar) is involved in a conspiracy to get rid of him and remarked that Marks "suspects that he might have to go" and was looking for "sympathy".

In a letter to the Customs chief, Luncheon has directed Marks to submit the information on the corruption and other matters he has promised to speak out about in its entirety to the Commissioner of Police, the Office of the President, the Chairman of the Integrity Commission and the Auditor General within 48 hours.

The 48 hours will expire tomorrow at 15:00 hrs, Luncheon said in the letter.

He has also advised Marks that any failure on his part to submit the identified information "will be considered tantamount to cover-up of corrupt practices."
