( CNN ) -- A Minnesota middle school student , with the backing of the American Civil Liberties Union , is suing her school district over a search of her Facebook and e-mail accounts by school employees . The 12-year-old sixth grade student , identified in court documents only as R.S. , was on two occasions punished for statements she made on her Facebook account , and was also pressured to divulge her password to school officials , the complaint states . `` R.S . was intimidated , frightened , humiliated and sobbing while she was detained in the small school room '' as she watched a counselor , a deputy , and another school employee pore over her private communications . The lawsuit claims that her First Amendment rights were violated by employees at Minnewaska Area Middle School , in west-central Minnesota , as well as her Fourth Amendment rights regarding unreasonable search and seizure . The Minnewaska School District denies any wrongdoing . `` The district did not violate R.S . 's civil rights , and disputes the one-sided version of events set forth in the complaint written by the ACLU , '' according to a district statement . According to the complaint , R.S . felt that one of the school 's adult hall monitors was picking on her , so she wrote on her Facebook `` wall '' that she hated that person because she was mean . The message was not posted from school property or using any school equipment or connections , the lawsuit states . Somehow , the school principal got a hold of a screenshot of the message , and punished R.S . with detention and made her apologize to the hall monitor , the complaint says . She was in trouble again shortly thereafter for another Facebook post , which asked who turned her in , using an expletive for effect , the lawsuit says . She was given in school suspension and missed a class ski trip . In the third incident , according to the complaint , R.S . was called in by school officials after the guardian of another student complained that R.S . had had a conversation about sex on Facebook . The girl was called to a meeting with a deputy sheriff , school counselor and an unidentified school employee , the court documents states . There , she was `` intimidated '' into giving up her login and passwords to her Facebook and e-mail accounts , the lawsuit says . `` R.S . was extremely nervous and being called out of class and being interrogated , '' the lawsuit says . The officials did not have permission from R.S . 's mother to view her private communications , and they gave the girl a hard time about some of the material they discovered , the lawsuit states . `` Students do not shed their First Amendment rights at the school house gate , '' Charles Samuelson , executive director for the ACLU in Minnesota , said in a statement . `` The Supreme Court ruled on that in the 1970s , yet schools like Minnewaska seem to have no regard for the standard . '' The school district maintains that such searches did not cross any boundaries . `` The district is confident that once all facts come to light , the district 's conduct will be found to be reasonable and appropriate , '' the district said .
