Lucknow: Uttar Pradesh Director General Karamvir Singh on Wednesday became the first officer in the last one decade to retire as police chief of the state known for frequently transferring police officers.

60-year-old Singh said that his focus during the tenure was to ensure that police stations become more and more efficient to deal with crime.

"It is not for me to judge. It's for the others to judge my tenure," Singh, a 1975 batch officer, who had a tenure of two years in the key post, said.

Singh is the first officer to retire as DGP of the most populous state of the country in the last 10 years.

The last IPS officer to retire as DGP was M C Dwevedi in 2001.

After Dwevedi, officers R K Pandi, Radhey Mohan Shukla, Haakam Singh, V K B Nair, Yashpal Singh, Bua Singh, G L Sharma and Vikram Singh became Director Generals of UP Police but had to leave midway following orders from the state government.

Director General PAC R K Tiwari would now hold additional charge of Director General of Uttar Pradesh Police.

Singh was Special Director General of CRPF in Kashmir during the time the Amarnath land agitation had hit the state.

Assembly elections in Jammu and Kashmir had also taken place during his tenure and the role of the para-military forces was appreciated.
