( CNN ) -- New York police say they 've found no evidence corroborating a claim by actress Amanda Bynes that she was sexually harassed after police were called to her apartment . `` A credible civilian witness who was with the officers throughout told investigators that none touched Ms. Bynes inappropriately or otherwise engaged in misconduct at any time , '' a NYPD Internal Affairs representative said . The incident is the latest in a series of run-ins with the law for Bynes , who had a squeaky-clean image as a teen actress . Officers were called Thursday to her building in Manhattan 's theater district after her building manager reported the 27-year-old was smoking an `` illegal substance '' in the lobby , police said . Bynes had headed back to her apartment by the time police arrived , but she let officers in when they knocked on the door , they said . Once inside , the officers noticed a bong and other marijuana paraphernalia sitting on a coffee table , which Bynes immediately started to throw out a window , police said . Police charged her with tampering with physical evidence , reckless endangerment and criminal possession of marijuana . The endangerment stems from the possibility that the tossed paraphernalia could have hit someone below . According to media reports , she appeared in court Friday and was then released until her next appearance in July . Taking to Twitter to make her case , Bynes said the police account is `` all lies . '' Her story is that she was `` sexually harassed by one of the cops the night before last '' -- the same police officer who , she wrote , ended up arresting her . Bynes said she had opened her window `` for fresh air '' and did n't throw out any drug paraphernalia . She insisted the officer lied when he said she did . Then , she alleged of the officer in her apartment , `` He slapped my vagina . Sexual harassment . Big deal . '' Bynes said she was handcuffed , `` which I resisted ... then I was sent to a mental hospital . Offensive . '' `` The cop sexually harassed me , they found no pot on me or bong outside my window , '' Bynes tweeted . `` That 's why the judge let me go . '' Bynes has a DUI case pending in Southern California , while a pair of separate hit-and-run charges against her were dismissed late last year . Earlier this month , the actress was sentenced to three years ' probation for driving on a suspended license . A young teenager when she burst on the scene as the lead in Nickelodeon 's `` The Amanda Show , '' Bynes also starred alongside Jennie Garth in the sitcom `` What I Like About You . '' She later scored roles in movies , including `` Hairspray '' and `` Easy A . ''
Civilian witness says no one touched the actress `` inappropriately , '' NYPD says . Bynes had a squeaky-clean teen image . The actress sloughs off cops ' account , says she had no pot .
