It’s actually 180 days. In this particular case it wasn’t about the limit. Romanian law has another provision: if you are not considered a “threat to society”, you can be investigated without being jailed. Normally, that means you walk free until your trial, with some restrictions on leaving the city or country, depending on your charge. However, if you are considered a flight risk while also not being deemed a “threat to society”, you will usually await trial under house arrest. No need to be rich or famous, just have a half-decent lawyer or a lenient prosecutor who doesn’t even ask for jail time to begin with.
