An imprisoned former broadcasting executive sued a Phnom Penh Municipal Court official on Monday for allegedly violating legal procedure by opening an investigation against him.

Former Southeast Asia TV and Radio (SEA TV) deputy general director Sem Sovandeth accused vice prosecutor Meas Chanpiseth of illegally charging him in connection to a complaint filed by SEA TV financial chief Ban Bunheng on August 2014, according to the lawsuit.

The complaint accused Sovandeth of stealing more than $1 million in funds from the company. Sovandeth, however, said that he has already been convicted for the same crime in 2010.

He is currently serving time in a Kandal prison for breach of trust and embezzlement. The lawsuit cited a Penal Code provision saying that any accused person convicted by the court could not be charged again for the same offence.
