Police arrested four suspected members of an outlawed group after a gunbattle in Karachi, a senior police official said yesterday. The men, arrested on Monday, were being held on charges of plotting attacks on Shiite Muslims, police said. They were members of Lashkar-e-Jhangvi, a militant group whose members were also implicated in December 2003 assassination attempts on President Pervez Musharraf. Police also seized guns, detonators, audio and video cassettes, compact discs, and religious literature after the gunbattle in Karachi's Mahmoodabad neighborhood. Manzoor Mughal, a deputy inspector general of police, said the suspects carried out at least three different attacks against Shiites in Karachi, killing over 20 people. "They (the suspects) were planning more terrorist attacks in the city," said Mughal.
