The police have recorded former prime minister Dr Mahathir Mohamad's statement, his lawyer Haniff Khatri Abdullah revealed today.

Speaking to reporters outside the Yayasan Al-Bukhary building in Kuala Lumpur, where the statement was recorded this morning, Haniff said the investigation is not specific to any issue.

"Investigations are being carried out in a general manner and not specific to a particular issue," he added.

Haniff also declined to comment on which section Mahathir is being investigated under.

Asked whether the police would record another statement from his client, the lawyer said that depended on the police.

"But for us, we believe there is no reason for the police to come again because all the issues that needed to be detailed have been done," Haniff added.

Previously, inspector-general of police Khalid Abu Bakar said Mahathir is being investigated under Section 500 of the Penal Code for criminal defamation.

This is in relation to police reports lodged over his remarks that Umno division leaders have taken money.

Mahathir made the statement during his appearance at the Bersih 4 rally on Aug 29-30.

The rally was held to press for Prime Minister Najib Abdul Razak's resignation.

Mahathir has repeatedly called on Najib to step down, accusing the prime minister of numerous misdeeds, including theft.

However, Najib has denied any wrongdoing and accused Mahathir of being part of a conspiracy to topple him.
