Police investigators on Tuesday submitted a plea before an anti-terrorism court (ATC) in Karachi, requesting the court to suspend the ongoing investigation into the Azizabad weapon recovery case due to lack of evidence, DawnNews reported.

The plea was submitted by an investigation officer in Karachi's anti-terrorism court on Tuesday, the plea also requested the court to categorise the case as 'A-Class' as police officials failed to produce and submit any substantial evidence.

The plea submitted by the police was accepted by the ATC, which will now decide over the matter.

If a case is categorised as A-Class, the investigation process of the case is suspended until any substantial evidence is submitted by law enforcement agencies (LEAs).

Last month, a huge cache of Nato weapons and ammunition was recovered by police during a raid on an empty house in the Azizabad area of the metropolis.

Police had seized a large number of weapons including anti-aircraft guns, SMGs, LMGs, sniper rifles, hand grenades and rocket launchers hidden in the water tank of the empty house.

Bulletproof jackets and helmets were also recovered during the raid by police.The raid was conducted after the police was tipped off by a political worker already in police custody.

“In light of disclosures made by a detained suspect, big-wigs of a political party provided help in procuring these arms and ammunition,” said the AIG Karachi while addressing the media after the raid, without naming the party and its leaders.

The city police chief had claimed that arms were supposed to be used by the elements residing in London particularly with cooperation of RAW (Indian intelligence agency) for terror activities in the metropolis but it was foiled through timely action by security institutions.

Sindh Chief Minister Syed Murad Ali Shah also indicated at the link of recovered large arms cache from a vacant house in Azizabad and a political party.
