A 41-year-old foreign currency trader was today ordered to serve a day's jail and fined RM4,000 or in default two months jail, after pleading guilty at the Sessions Court in Kuala Lumpur to making a Facebook posting that is demeaning on Prime Minister Najib Abdul Razak.

Mohd Nasaruddin Saron, a second generation Felda settler from Kota Tinggi, Johor, made the offending posting on his Samsung Galaxy Tab on Oct 26, last year, which was "viewed and caused anger on a member of a public, the next day."

In the posting, Mohd Nasaruddin, among others, blamed the country's leader for the rising prices and the implementation of the Goods and Services Tax (GST).
