Patna, Mar 28 (IANS): Gangster Makhan Dada has served an extortion demand of Rs 50 lakh on the Superintendent of the railway station in Bihar's Nawada and threatened to eliminate him and the railway gate operator if it was not paid, officials said on Tuesday.

In a letter in Hindi to the official, the gangster said: "Savinay nivedan hai ki Rs 50 lakh rangdari diya jaye, nahi to Bade Babu and gateman ko goli maar di jayegi (You are kindly requested to pay Rs 50 lakh as extortion or the senior official (station manager) and the gateman will be shot dead)."
