Extra police will be deployed for Sunday's Malaysia FA Cup quarterfinal in Johor Bahru after some provocative social media postings by rival fans.
Defending champions Johor Darul Ta'zim (JDT) will hots fierce rivals Pahang in the second leg, with the visitors holding a 3-1 advantage from the first leg on April 1.
Johor Baru Selatan police chief Assistant Commissioner Sulaiman Salleh says 1,124 police personnel will oversee security at a packed Larkin Stadium.
"There must be no explosives. No weapons, No provocation or clashes between the fans. No rally. No illegal assembly before or after the match and no alcohol consumption at the stadium, or prior to the start of the game," Sulaiman told The New Straits Times.
"[There have been] some provocative postings by fans that can lead to conflict and trouble."
