Unidentified miscreants shot three bullets one of which pierced the glass panes of the window and landed at the court of the chief judicial magistrate, police said.
However, none was injured as the court was not in session.
The other bullet misfired.
Papiya Sarkar, who is the wife of district court advocate Chanchal Sarkar, received a bullet injury on her leg in the attack which took place next to the public prosecutor's office.
