The Home Ministry has ordered the police to probe a party which was said to have duplicated the national coat of arms.

Its minister, Hamzah Zainudin said it is an offence to imitate the coat of arms under Section 3(1)(a) of the Emblems and Names Act 1963.

"I have instructed the police to carry out the investigation and to take stern action immediately.

"The government will not compromise with any party who performed this unpatriotic and irresponsible act," Hamzah said in his Facebook posting today.
