A woman who called herself Kim Hyun Joong's girlfriend has filed assault charges against him at the Songpa Police Station. The police are gathering evidence to substantiate her relationship with the star and to document her injuries.

The charges are serious. The woman alleges that the singer and actor repeatedly assaulted her from the end of May through mid-July.

According to the woman, referred to as 'A,' the two began dating in 2012. In May they argued about his interactions with other women. She alleges that he punched and kicked her on her face, arms and chest and that these injuries resulted in a trip to the emergency room. 'A' said that she was told the injuries would take two weeks to heal.

'A' says that Kim Hyun Joong apologized after the incident and they continued to date.

In July she says that the couple supposedly argued again about the same topic and she says that he assaulted her again. This time she says she went to the hospital where she was diagnosed with a fractured rib. She says that she was told that the injuries would take six weeks to heal.

In the past Kim Hyun Joong has spoken about his reluctance to hit others, even on set. In an interview with the KBSTV2 show "Entertainment Tonight," he said that it was hard to even pretend to hit another actor because he imagined how much it would hurt.

"I just couldn't do it right because I was thinking of how much pain the other actor would be in," he said. "I just felt so sorry and so I hesitated a lot. As a result, I got a lot of bad takes."

Until all the evidence is in, the police say it is merely a one-sided allegation.

"We are currently investigating the case," said a police statement. "It is not yet concluded if the defendant is guilty."

Key East Entertainment took a day to make an official statement regarding Kim Hyun Joong's side of the dispute. According to the agency the two parties have known each other since 2012 but did not start dating until a few months ago when they argued and in the heat of the moment things got physical. It is not true that there were repeated physical assaults.

According to a KeyEast representative, the couple fought once and the woman did not fracture her ribs during that argument but the injury happened while the couple was playing around. She did not even notice the injury right away.The agency expressed their disappointment that such one-sided reports were making headlines.

"The truth is being exxaggerated," said a Key East rep.They also said Kim Hyun Joong is working with the police to help reveal the truth.

The "Inspiring Generation" star has not yet been summoned by the police and will hold a concert in Thailand as scheduled on Aug. 23.
