PKR vice-president and Batu MP Tian Chua has been found guilty of insulting a police officer's modesty and fined RM3,000, which could see him barred from contesting in the next general election.

Petaling Jaya Sessions Court judge Yasmin Abdul Razak said the court was satisfied that the prosecution had proven its case beyond reasonable doubt.

Tian Chua was charged in August 2014, under Section 509 of the Penal Code, with uttering swear words at police personnel in April the same year.
