Selangor and Johor police said today they have stepped up security in the states following the bomb attack in Jakarta on Thursday.

Selangor Police chief Datuk Abdul Samah Mat said security was being beefed up at public places such as shopping malls, entertainment outlets, tourist attractions and entry-exit points such as airports and ports.

He advised the people in the state not to be unduly worried as the security situation was under control.

“The people should not spread unverified information on the security situation via social media or other means. They should notify the police should they come across anything suspicious in their areas,” he said in a statement.

In Johor Bahru, Johor Police chief Datuk Wan Ahmad Najmuddin Mohd said security had been beefed up at shopping malls, entertainment outlets and entry-exit points.

He said all district police chiefs had been instructed to step up security in their areas of jurisdiction. In the bomb attack last Thursday in Jakarta, five militants and two civilians were killed outside the Sarinah Mall in Jalan MH Thamrin in the heart of Jakarta.

Following the incident, Inspector-General of Police Tan Sri Khalid Abu Bakar said the police had raised the security alert to the highest level in Malaysia.
