KARACHI: A protest staged by the Pakistan Tehreek-e-Insaf (PTI) Wednesday night here at the city's Shahrah-e-Faisal ? in favour of the sugarcane farmers ? has concluded, leaving six police officers wounded.

Two of the officials beat up by PTI workers are in critical condition.

The old Metropole Hotel area and the nearby roads were consequently opened for traffic late night.

The participants of the rally that had come from Hyderabad earlier had also joined in the political party's demonstration near Abdullah Haroon Road.

Authorities, in order to disperse the protesters, had made use of baton-charge as well as tear gas shelling.

A prior demand ? to let go of the detained PTI leader Haleem Adil Sheikh and numerous others ? was met, and the arrestees released.

It was on Sindh Home Minister Sohail Anwar Siyal's orders that the party members were beaten up, Sheikh alleged, warning that if the farmers are not offered adequate rates ? the primary reason for the protest ? the demonstration will continue.
