Demanding justice, prominent artists of the Bengal music industry protested on Monday against the alleged rape and murder of a trainee doctor at Kolkata's RG Kar Medical College and Hospital. On Monday evening, several artists, including actor Saheb Chatterjee, radio personality Mir Afsar Ali and others, came on the streets to express their outrage over the matter.

Speaking to ANI, actor-singer Saheb Chatterjee expressed his feelings.

He said, "Bring the culprits in front of everyone and give them maximum punishment, which will remain an example that in the future people will think twice before doing such an act. This is such a big issue. This is not only India's or Kolkata's issue but an international one. We are here to protest and demand justice. We need complete justice; we don't want half-truth."

Singer Soumyojit stated, "We have become so eager for justice and we want this system to change. May we all get justice. We artists today are here to protest and demand things in our own ways."

Radio personality Mir Afsar Ali added, "People have forced us to come on roads. Here, we are all are artists and we are associated with the creative field. We want to express our feelings after witnessing such a case. We want to show that we are also humans. We can't function when there is so much disturbance around us. If anybody takes action or not, I think it's our duty to raise our voice."
