Although describing Jamal Md Yunos as a "clown", PKR vice-president Rafizi Ramli said it will not be rib-tickling if he was arrested over the red shirts movement leader's police report.

"Ha3 but I just realised I may be summoned to give statement or detained to assist investigation," he tweeted.

"Yang tak lawaknya: lepas ni silap2 hari saya kena tangkap polis sebab nak siasat laporan Dato' Jamal. Tak gentleman la Dato' Jamal ni (What is not funny is that if after this, I get arrested by the police to investigate Jamal's report. Jamal is not a gentleman)," Rafizi added in his tweet.

This afternoon, Jamal told reporters that some of the information he had obtained on the alleged link between Bersih and Islamic State had come from Rafizi.

Jamal also lodged a police report on the matter.

In an immediate reaction, Rafizi rubbished the allegation and called the Sungai Besar Umno division chief as the "biggest clown in Umno", whose antics are no longer comical.

However, on Twitter, the PKR leader could not help but wonder if Jamal was an "evil genius", and had some admiration for Jamal's diabolical scheme.

Responding to one Twitter user, Rafizi said he would not sue the red shirts leader over his allegation as the latter is "crazy".

"If I win what will he pay? (But he has a lot of sponsor from Dubai)," he added.

Bersih has denied the terror link allegation and revealed it is considering suing Jamal.
