According to The Star, Inspector-General of Police Tan Sri Khalid Abu Bakar said yesterday that there was "no such thing" although he added that the police will be on standby for any untoward incidents.

Rumours have been circulating on social media that leave for police personnel has been frozen, possibly in anticipation of a need to mobilise the force in the event of any street clashes.

The rumours followed announcements by local activists over plans to hold at least two rallies in the capital — one this afternoon and a second this month-end — both to call for Prime Minister Datuk Seri Najib Razak's early resignation.

Yesterday, police arrested youth activist Adam Adli Abul Halim and PKR Youth member and former student activist Syukri Rezab over their involvement in plans for today's afternoon rally.

Prior to his arrest, Adam said he had already explained to the police that the rally would be peaceful, and that he would ensure everything goes smoothly.

Earlier, Adam had said that a youth group calling itself Demi Malaysia who are the rally organisers are expecting a turnout of some 500 people and urged those attending to dress in white.

He said similar street assemblies had been in the city previously without disrupting the harmony of the country.

Adam said the #TangkapNajib rally will be the precursor to bigger upcoming protests to demand Najib resign for his alleged involvement in the debt-riddled 1Malaysia Development Berhad (1MDB).

Earlier this month, US daily Wall Street Journal reported nearly US$700 million (RM2.6 billion) was funnelled through 1MDB and into bank accounts purportedly owned by Najib ahead of the 2013 May general elections.

Najib has yet to deny or confirm the allegation.
