Dear mengya2008,
As I had stated in Singapore, it is always prudent and wise to have a written agreement for rental of premises even though it is for a very small room or area.
Also when he failed to give the required notice and you are terminating his notice, you should give him something in writing to evince your intention to forfeit his deposit.
Your erstwhile tenant had committed severed offences but in cases like that the police has a discretion whether to prosecute.
Now for the disturbance, make a police report (which you have done) and issue him a lawyer’s letter (which Is recommended), and followed by making a Magistrate Compliant.
This is done by going down to the Criminal Registry of the Subordinate Courts and lodging a complaint against the perpetrator. The Court will summon him to court and will try to mediate between the parties. Oftentimes the perpetrator to avoid trouble with the law will undertake not to commit the offence again and that is the end of the matter. If that does not work, the victim can make a private summons against the perpetrator. i.e. take on the role of the prosecution (检察院) and bring charges against the perpetrator. If found guilty and convicted he might be fined or sentenced to jail or both.
