Delhi Police — complaint against police personnel taken loan

Hi,
I want to complaint against delhi police personnel

Name:mr pawan kumar tyagi s/o shukardhan tyagi

P. S. No. 28031274
Belt no. 6202

Present add. B-3201, street no.81, sant nagar, burari delhi

Permanent add. Village & post. Strata distt. Meerut up.

Mr. Pawan had taken a loan of amount 5 lakh in 2006. But he did pay a amount of 2.5 lakh.
Still he has to pay 2.5 lakh + intrest.
But he did not gave installment since 2008. And the loan account became npa (Non performing assets).
We are try to pressurise him through call and do many requests, but he always says that he will not give the loan installment and threatening words to us (Dhamki deta h ki tm kuch nhi kr skte mera like that).

Our only hope is you i. E. Delhi police.
Please do the needful.

Regards,
