An opposition lawmaker said Wednesday he has found the residence of the daughter of President Park Geun-hye's close confidante at the center of the ongoing influence-peddling scandal.

Rep. An Min-suk, a lawmaker of the Democratic Party, told CBS Radio that he found Chung Yoo-ra's residence in Germany during his recent trip to the country. Korean residents there are currently standing by at the location, he added.

The discovery is expected to help speed up the parliament's investigation into the case. She has refused to attend a National Assembly hearing on the case.

Chung, a former member of the national equestrian team, was accused of receiving unlawful favors from her high school and university under her mother Choi Soon-sil's influence. Chung was presumed to stay in Germany, but her exact whereabouts remained cloudy.
