Some 53 militant suspects were arrested in different parts of Pakistan's southern port city of Karachi in police's raids during last 24 hours, said local police late Sunday, adding that one suspect was killed in the operations.

Adeel Chandio, the superintendent of police in Karachi, said that police and law enforcers conducted raids after getting intelligence tips about the presence of militants and criminals belonging to different groups in various areas of Karachi, the capital of the country's southern province of Sindh.

According to the details, three suspects were taken into custody during a crackdown in Darakhshan area of the metropolitan.

Police and Rangers cordoned off the Layari area, once considered as a safe haven for drug paddlers, extortionists, and militants, and successfully arrested 50 suspects.

However, during a raid in Chakiwara area of the city, some unknown suspects opened fire at police party to avoid arrest, but in retaliation, one suspect was killed while his companions managed to escape from the site.

Police said that the arrested were involved in several incidents of militancy and street crimes in the city.

The detained persons have been shifted to undisclosed locations where they are undergoing investigation.

Police, paramilitary forces and intelligence agencies are on high alert and have sped up raids in the densely populated Karachi since the arrest of the chief of a terrorist group of Ansar-ul-Sharia Pakistan last week.
