Sorry folks, I rushed and worded my two previous post badly and requested they be removed to give a better answer.
Yollam, your (partner?) has been arrested and interviewed for his/her suspected in involvement in an offence and released on bail for police to further their investigation and/or seek advice on whether he or she should be prosecuted (sent to court to answer/defend the allegation/s). If the decision is to prosecute then the accused would normally be 'charged', that is, instructed to attend court in the next few days.
A person does not need to be arrested to have to be sent to court for their suspected involvement in an offence, they can be investigated by police and 'reported' to the relevant prosecuting agencies to decide whether they should be prosecuted. If it is decided they should be prosecuted then they will receive a summons by post instructing them what time/date and court to attend.
The police have decided to report your (partner?) on this occasion and will be released from bail when he/she attends the local station.
hope this makes sense.
