On February 21st, singer Jo Sung Mo's agency, S-Plus Entertainment, denied all rumors of the singer reporting that he had been assaulted and verbally abused by his agency. After being hit with a lawsuit by S-Plus earlier this week,� representatives of Jo Sung Mo responded by claiming, "Around January of 2010, after Jo Sung Mo contracted with S-Plus, the CEO's attitude suddenly changed.� Him and his manager frequently assaulted and verbally abused him.� April of that year, they forced him to sing for a drama OST whether he wanted to or not, and did not pay him for his work as well." A representative of S-Plus spoke with OSEN and clarified, "We examined Jo Sung Mo's official statement, but the claims he made, such as assault, verbal abuse, swearing, and blackmail are all groundless.� If there is any truth to uncover, it will be uncovered in court.� S-Plus will be releasing our own official statement regarding his soon."
