New Delhi, May 18 (IANS): A Delhi court on Monday extended the judicial custody of disgraced Jammu & Kashmir Police officer Davinder Singh for another month.

Singh was nabbed while ferrying two Hizbul Mujahideen terrorists on the Srinagar-Jammu national highway, earlier this year.

He is currently lodged in Hira Nagar Jail in J&K and was produced before Special judge M K Nagpal through video conferencing after which the court extended his custody till June 16.

Besides Davinder Singh, three other accused -- Javed Iqbal, Syed Naveed Mushtaq and Imran Shafi Mir were also produced before the court through video conferencing, pursuant to which their custody was also extended till June 16.

Delhi Police's Special Cell had brought Davinder Singh from Hira Nagar Jail to the national capital in March for interrogation in another case.

Police had earlier told the court that Mushtaq, who is the Shopian district commander of Hizbul Mujahideen, along with other militants, were planning to execute a terror attack in Delhi and other parts of the country and targeted killings of protected persons.

In connection with this, the Delhi Police had filed an FIR which stated that youths in Jammu & Kashmir and Punjab are being trained for carrying out terrorist activities.

Davinder Singh was taken in custody under this FIR and was also interrogated regarding the Khalistan angle.
