Yup said before, mate went through the same thing, went through a sexual assault case which was absolute BS but they didn't even charge him, just kept pending the investigation for 6-7 months, guy couldn't leave the country and they took his phone away...all for them to say they're dropping the charges due to lack of evidence, utter BS.
This happened to my wife’s nephew. The girl completely made up the story. The witnesses (her friends!) told the police she was lying. The “investigation” lasted for a while, basically because the girl’s parents threatened police with a lawsuit if they didn’t press charges.
Actually, the police never directly informed us the investigation was completed and there would be no charges. We just never heard from them again. It’s been over a year.
