was this "victim" a minor under the law? How many young employees are you "counseling" and what exactly are your job duties? Unless discussing family issues fall under those, your employer is in the right to suspend you while an investigation occurs and that can include your personal belongings that are on their property (Especially if you signed a policy that stated that anything you brought onto their property could be subject to a search and/or seizure)

Even if the complaint is not found to be one that the EEOC wants to take up, they will give the complaintant a right to sue letter and then that person has to find an attorney to take a case and file a lawsuit against the employer. Your employer can often be held responsible for your actions, therefore it is in their best interests to STOP the behavior -- sometimes that means locking the employee out of their office and away from anything that they have left there.

You can send a request to their HR/legal team with a list of personal belongings and see how they react.
