In Kerala, police in Kochi have arrested Yusuf, a key accused in the Kozhikode twin blasts case. Police sources said he was picked up near Ambalamedu in Kochi. Yusuf, a native of Parappanangadi, was a close associate of Thadiyantavide Nasir, a Lashkar-e-Toiba activist, who was arrested recently in Bangladesh. Yusuf played a key role in the bomb blasts that took place at two bus stations in Kozhikode in 2006. The case is now being investigated by the National Investigation Agency.<br/>
