South Korean actress and model Jung Chae-yul has been found dead in her apartment. She was 26.

Chae-yul’s death was announced by her management company on Tuesday, although the cause of her death is still unknown.

“We are here to deliver heartbreaking news. Actress Chaeyul has left us,” Chae-yul’s agency, Management S, told MK News, as translated by Koreaboo.

“Her funeral will be held privately in accordance to the wishes of her family, who must be in greater sadness than anyone else,” the statement continued. “We hope you pray for the deceased so Chaeyul, who was also sincere in her acting, may rest in peace.”

“Our Chae-Yul was very hardworking. She was a deep-hearted and cool friend,” the CEO of Chae-Yul’s management agency told OSEN, according to the Independent. “In my opinion, it is hard to describe in words how amazing she was as an actress.”

The star made her debut as a model in the 2016 reality series, “Devil’s Runway,” but more recently shot to fame for her role in the South Korean comedy “Zombie Detective.”

She was in the midst of filming the upcoming K-drama series, “Wedding Impossible,” in which she had a leading role.

The cast and crew have ceased filming until at least Wednesday.

Fans of the actress have taken to social media to grieve, leaving comments on her recent social media posts.

“Rest in peace angel,” one user wrote.

“I wish you all the best there and only good memories,” wrote another. “I’m so sad. I don’t know how to feel.”
