Police will summon computer programmer Azharuddin Othman, who is believed to have sold data on the population, with the aim of forging signatures for the 'Citizens' Declaration.'

Deputy Inspector-General of Police, Datuk Noor Rashid Ibrahim said they will conduct an investigation and collect information on the case.

"Police will summon him within two or three days to assist investigation and will scrutinise the information before taking further action," he told reporters after closing the Royal Malaysian Police Al Quran Recital Competition at Wisma Darul Iman here, today.

On May 26, Azharuddin made a statutory declaration that he sold data on the population to Syarul Ema Rena Abu Samah (Ratu Naga) meant for the 'Citizens' Declaration.'

Noor Rashid said it is an offence for anyone to spread and sell information in the population database as it is classified as confidential and only certain people are entitled to have access to them.

"The spread of confidential information by any party is a violation of the rules and action can be taken under the Official Secrets Act (OSA)," he added.

Azharuddin, 30, claimed that he sold information in the population database to a woman known as 'Ema' for RM5,000 but was only paid RM1,000.

The woman claimed she needed to collect 1.2 million signatures for the 'Citizens' Declaration' meant to topple the government of Prime Minister Datuk Seri Najib Razak.
