Supreme Court on Thursday morning upheld the verdict in actor Sanjay Dutt’s case in the 1993 Mumbai blasts. Dutt has already spent 18 months in jail and now has four weeks to surrender.

The Munnabhai series star is required to be behind bars for the remaining 3 and a half years.

On hearing the verdict, Bollywood stars took to twitter to express their shock. Filmmaker Mahesh Bhatt tweeted: “Heart Broken: Just heard that Sanjay Dutt has to go to jail for 5 years. I expected mercy! Alas it did not happen.”

The actor was convicted in November 2006 for illegal possession of a 9mm pistol and an AK-56 rifle but was acquitted of more serious charges of criminal conspiracy under the now defunct anti-terror TADA. The serial blasts in Mumbai over 12 locations in the city killed 273 people and injured 713.
