If you've received summons under section 341 and 326 IPC for wrongful restraint and Voluntarily causing grievous hurt by dangerous weapons or means from police, you'll need to appear before the Police station as Section 326 is a cognizable and non-bailable offence.
If you won't cooperate with the investigation, then they'll get warrants issued in your and compell you to join the same.
It's advisable that you appear in the concerned Police station on the date mentioned on the summons with an advocate. Going there alone would not be advisable.
For any other queries, feel free to contact.
Regards.
