An aide filed a report at the Dang Wangi police headquarters on Aug 18 over two alleged defamatory articles implicating him in the incident and a scandal involving a private company.

“A report has also been filed with MCMC and Facebook so that immediate action can be taken against the page and its administrator or owner,” the former Umno vice-president said in a statement.

Ismail said the contents of the postings were “completely untrue and maliciously intended to damage my reputation and good name”.

He urged the authorities to carry out a thorough investigation and take firm action against the owner or administrator of the Facebook page, as well as anyone spreading the postings concerned.

“I have also instructed my lawyers to take further legal action against those involved.

“I thank Rafizi for his explanation on the matter.”

Rafizi’s 12-year-old son was attacked at a shopping mall in Putrajaya last week.

Rafizi said CCTV footage showed that two men, dressed in black with their faces fully covered by helmets, had followed his wife’s car on a motorcycle.

His son, who was dragged and stabbed with a syringe, was rushed to hospital for treatment and a check-up. The assailants escaped.

The former economy minister said he suspected the attack was planned, and that his wife was likely observed by the assailants for a few days before the incident.

He also believed it was a warning for him not to speak out on certain issues.

Earlier today, Rafizi denied claims linking Ismail and former health minister Khairy Jamaluddin to the attack on his son.

The former PKR deputy president said there were allegations a week before the attack that information was provided by a whistleblower about a money laundering case supposedly involving Ismail.

He said there were also claims the information concerned projects linked to Khairy during his time in the health ministry.
