Dhanbad (Jharkhand): Political temperature in Dhanbad is at its peak these days and it is incomplete without discussing Singh Mansion, the place which remained the power centre for decades.

It was built by Suryadev Singh, who came to Dhanbad in search of a job in the 1950s and started working under the then coal mafia leader B.P. Sinha. After Sinha was murdered, Suryadev Singh overtook the business of his late boss and became a don of the coal fields.
