It seems he is being investigated under the Sedition Act.
I believe Bernama is referring to blogger Sheih who posted his "Nation In Distress" in his blog Kickdefella on Aug 4
Bernama's mention of the police action was in the last paragraph of its report below:
Laws Needed To Protect Country's Symbol
BUKIT MERTAJAM, Aug 22 (Bernama) -- Malaysia should have laws to protect the country's symbols to ensure that they are not toyed with, Deputy Entrepreneur and Cooperative Development Minister Datuk Saifuddin Abdullah said.
"Prior to this, the Negaraku had been toyed with and now there are people suggesting that the Jalur Gemilang be flown upside down. We must take action to teach those intending to fool around with the country's symbols a lesson," he told reporters after launching the "Fly the Jalur Gemilang" campaign at the Butterworth-Kulim highway toll plaza here Thursday.
He said that although it was not the best solution, action must be taken against those who disrespected the country's symbols, like the flag and anthem.
On Aug 4, a blogger suggested in his blog that the people fly the national flag upside down to show that the country was in a state of "emergency".
Prime minister had described the blogger as ill-mannered.
Police are reported to be investigating the blogger under the Sedition Act.
The Sedition Act?
Was it because the PM actually referred to Sheih's posting as "evil"?
