Christopher Tymczak was arrested Tuesday. Prosecutors said the arrest happened at a motel and that one officer was playing the role of a prostitute. When another officer tried to make an arrest, Tymczak punched that officer, according to the Harris County District Attorney's office.
Tymczak is involved in a separate discrimination lawsuit against TSU and he was also charged with forgery in September.
According to TSU officials, Tymczak is still employed with the university.
"We are disappointed to learn of the charges that have been filed against Dr. Tymczak. All University employees, including TSU faculty members, are expected to adhere to all laws and regulations, as well as all University policies and procedures. Dr. Tymczak will be afforded his due process in the legal system. The University is reviewing the matter to determine if there were any violations of University policies or procedures," TSU spokesperson Eva Pickens told Eyewitness News.
