The Special Cell of Delhi Police on Thursday sought from a Delhi court more time to investigate the role of Indian Mujahideen co-founder Yasin Bhatkal and his accomplice Asadullah Akhtar in one of the blasts in the 2008 serial strikes in Delhi.

In an application moved in the court of Additional Sessions Judge Daya Prakash, the Special Cell said it is still investigating the role of Bhatkal and Akhtar in the blast that took place in an autorickshaw at Beadonpura, Karol Bagh, here on September 13, 2008.

It sought further 45 days for completing the investigation against the duo as the 90-day statutory period of filing the charge sheet is set to expire on March 10. The two accused were arrested by the police in this case on December 10, 2013.

Both Bhatkal and Akhtar are at present in judicial custody and are named as accused in a series of terror cases, including the 2010 German Bakery strike, Chinnaswamy stadium blast and the Jama Masjid shoot-out.
