Delhi Police is interrogating an associate of the prime accused in the Kavita Rani murder case who was arrested in Central Delhi on Tuesday night.

Triloki Singh, an associate of prime accused Ravindra Pradhan, was arrested near Videocon [Get Quote] Towers in Paharganj area, police said.

Singh has been handed over to the Meerut Police on Wednesday morning, a senior police official said.

The name of the 37-year-old headman of Dhanera Kirat village in Uttar Pradesh's Bulandshahr district also figures in threat letters received by Kavita Rani, a lecturer in the Chaudhary Charan Singh University of Meerut who was murdered in late October.

Besides the Kavita Rani case, Singh was also wanted in two other cases in Uttar Pradesh.

The disappearance of the 29-year-old lecturer came to light about four days back and the pradhan, who was arrested from a television studio in Noida, had admitted to have murdered Kavita.

Pradhan said that he, along with his accomplice, strangulated Kavita and disposed of the body in a canal in Sanauta in Bulandshahr following an altercation.
