Outside Sen's offices, factory and his retail shop, slogans and graffiti filled the walls. Strikes were staged on a regular basis in the garment factory, which brought work to a complete halt. In the silk screening and silk block print factory, truckloads of merchandise ready for export were set on fire. During all of this, the local police refused to help, and Sen's business was destroyed by the CPI(M) leadership and he was forced into bankruptcy. False cases were initiated against him and his house and office were raided repeatedly by the police and their assets seized. His bank accounts were frozen and all cash at home was confiscated by the authorities. The stress of this intense harassment brought on early onset of dementia at the age of 50.
