Kolkata police has arrested one of its sub-inspector Shankar Chakraborti for smuggling out ammunition from police armoury.
Chakraborti was remanded to police custody for four days by a court on Tuesday.
He had been selling ammunition to criminals for nearly two decades said a top police official.
"He built up a racket to collect ammunition issued for practice firing at the camp. Probably, he used to collect the bullets from the trainees, who did not complete their quota of practice firing," he added. Chakraborti was selling a bullet for Rs. 100. The arrested SI who was working in the CID had a rapport with local criminals looking for ammunition.
