He was, but if I recall correctly the Romanian law has a limit of 3 months (?) they can keep someone in jail waiting for the case. As much as I (dis)agree with the sentiment of "jail is for poor people", this is not the case here.

That’s a very good thing. In the US there are people who spend years in jail just waiting to be charged. Some wait so long that by the time they’re charged they’re coerced into playing guilty because the time they already served would be less than the crime so they’re allowed to be free immediately if they plead guilty. If they want to maintain their innocence they’d have to stay longer to wait trial. I have no clue how it’s constitutional.
