Pakistani protesters call for officer's arrest after killing

Thousands of Pakistanis are rallying in the port city of Karachi to demand the arrest of a police commander charged with killing a 27-year-old aspiring model.

Rao Anwar went into hiding after he and other officers killed Naqeeb Ullah earlier this month and then tried to cover it up, saying that Ullah was a Taliban militant killed in a shootout.

An investigation later found that Ullah had no ties to the militants. The motive for the Jan. 13 killing remains unclear.

On Thursday, some 3,000 protesters from Ullah's tribe vowed to continue their sit-in until Anwar is arrested. Anwar has been relieved of duty and barred from leaving Pakistan. Police have carried out several raids while looking for him.
