Beldanga railway station complex in West Bengal's Murshidabad district was set on fire by thousands of people protesting the amended Citizenship Act.
The murders took a political turn after BJP spokesperson Sambit Patra tweeted the video of the crime scene and said the deceased Bandhu Prakash Pal was an RSS worker.
Bandhu Prakash Pal, a 35-year-old teacher, his pregnant wife Beauty and 8-year-old son Angan were found dead in their house at Jiaganj in Murshidabad district on October 8, when Durga Puja festivities were on.
Bengali actor and director Aparna Sen on Friday termed the murder of RSS worker and his family as 'gruesome act' and said it was 'shame on us'.
