Police arrested Mohammed Junaid, allegedly the operations chief of Harkatul Mujahideen Al-Almi, on Monday after a gun battle here, said a senior police official Raja Omar Khitab. Police launched a raid as Junaid and an accomplice were shifting weapons from a hideout in the city. The two militant suspects traded fire with police, before Junaid was captured while the other man got away. Police confiscated one AK-47 assault rifle, two grenades and a pistol.Khitab said Junaid was wanted in connection with several attacks on police and a 2003 bombing at a private club in Karachi that injured nine people. The government had offered a reward of Rs 500,000 for information leading to his arrest. Harkatul Mujahideen Al-Almi emerged as an offshoot of Harkatul Mujahideen, a banned militant group that fights against Indian security forces in Kashmir and is suspected of ties with the Taliban militia in Afghanistan.
