A non-governmental organisation has lodged a police report against former prime minister Tun Dr Mahathir Mohamad for attending the Bersih 4 rally at the Dataran Merdeka in Kuala Lumpur yesterday.

The report was made by the Non-Pensionable Army Veterans Association of Selangor at the South Klang district police headquarters here.

Association president Raja Kamaruddin Raja Ab Wahid said Dr Mahathir's attendance in the rally was akin to encouraging the people to participate in it.

"The question is, why did he have to go to the illegal rally? In my opinion, it was not necessary...he should not even have turned up.

"When Dr Mahathir arrived, people who gathered there indirectly, likened his presence as that of a 'head'," he told reporters after lodging the report.

On Saturday, Dr Mahathir attended the gathering, accompanied by wife, Tun Dr Siti Hasmah Mohamad Ali.
