Deputy inspector-general of police Noor Rashid Ibrahim said the Sept 16 rally by the red shirts is barred due to security reasons, Bernama reported.
He added organisers had not sought permission from the police as yet, but no approval will be granted.
"If the rally proceeds, the police will control and ensure they do not disturb or destroy property or people carrying out their daily activities in the area," he was quoted as saying.
He said 2,000 police personnel would be deployed to control the rally.
The rally, reportedly planned to be held at the Bukit Bintang and Petaling Street areas, is meant to counter the Bersih 4 rally held on Aug 29 and 30.
Critics said the Bersih 4 rally, which among others called for the resignation of Prime Minister Najib Abdul Razak, was a Chinese-dominated rally and an insult to the Malay community.
The rally is backed by 500 Malay NGOs to show Malay unity and defend Malay dignity, Gabungan NGO-NGO Malaysia chairperson Jamal Md Yunos told Utusan Malaysia .
The group expects 300,000 people to turn up for the rally.
Jamal told the daily there is no reason for authorities to stop their, given that it did not crackdown on Bersih 4, even though it was held on the eve of National Day.
"This rally (on Sept 16) will take place, come what may, be it rain, storm or earthquake," he is quoted as saying.
Jamal ( photo ) snidely thanked the Bersih 4 rally-goers for carrying placards which "insulted Malay leaders" through their placards, prompting Malays to unite against this.
The Sept 16 rally will take place at Bukit Bintang and Petaling Street, where most traders are from the ethnic Chinese community, as payback as the Bersih 4 rally was held in an area where most traders were Malay, he said.
He said Bersih organisers had never considered the livelihoods of traders in the Masjid India and Jalan Tuanku Abdul Rahman area when they called for their rallies there.
"We have been quiet all this while, but it does not mean we were not angry. We were just heeding the authorities and the law by not taking to the streets. But this time, we will no longer bow down, we will gather," Jamal is quoted as saying.
Police said yesterday they have opened a sedition probe over the posters for the rally, which features a man in a silat pose with the words 'tanah tumpah darahku' .
A line from the national anthem to denote loyalty, the words literally mean 'the land where my blood spills'.
MCA has condemned the rally as a threat to racial harmony.
