Government inspectors are reopening 1,300 police files in Horst to see whether nine suspended police officers falsified information, reports the Limburger.
It says that all files between 2015 and 2019 which involved these officers are being re-examined. The agents were suspended for dereliction of duty and unprofessional behaviour.
Reports suggest that the investigation, which started last October, is examining whether police officers themselves made reports to an anonymous tips line and whether search warrants followed procedure.
The investigation could lead to a criminal case against the officers or the re-examination of previous judgements.
