Pakistani police said today they had arrested a key Islamic militant in connection with last week's bombing outside a church in Karachi and seized a huge quantity of explosives.
Mr Shamim Ahmed (25), the alleged operations chief of the outlawed Sunni Muslim group Lashkar-e-Jhangvi, was arrested in an overnight raid in a middle-class neighbourhood of Karachi.
The information he gave them prompted police to raid a house in the centre of the city, where they seized a large quantity of explosives and weapons, including hand grenades and letter bombs.
Mr Jameel said Mr Ahmed was suspected of involvement in Thursday's bombing outside Karachi's Anglican cathedral in which 11 people were wounded. A police officer described Mr Ahmed as a bomb-making expert.
Two unidentified militants threw a grenade outside the Holy Trinity Cathedral on Thursday, and a car bomb exploded as security officials searched the site.
