Production of "Housewife Detective," a South Korean drama starring actress Jang Na-ra and 2PM's Chansung, has been suspended due to budget issues, sources said Thursday. 

"We're waiting for filming to resume, as the production company has asked us to wait amid production cost issues," said a representative of one of the lead stars, who asked not to be named.

The unfinished drama is about an single mother going through economic difficulties working as an assistant to a private detective. TV industry insiders said that production has been suspended since March.

MSTAR Media Group, the show's production company, had planned to wrap up filming in the first half, and air it simultaneously at home and abroad. In addition to the budget issue, the company is also having difficulty in finding a network that will broadcast the show.

Outside of South Korea, Jang has enjoyed a successful acting career in China, appearing in hit Chinese dramas "My Bratty Princess," "Good Morning Shanghai" and "Unruly Qiao." (Yonhap)
