REPUBLIKA.CO.ID, PESHAWAR -- Police in northwestern Pakistan on Monday arrested six people accused of gunning down a Sikh political figure, attributing the killing to rivalry rather than a Taliban attack, as the militants had claimed.

Gunmen shot and killed Soran Singh, a prominent leader of Pakistan's tiny Sikh religious minority and a lawmaker from cricket legend Imran Khan's opposition Pakistan Tehreek-e-Insaf party, outside his home in the town of Buner on Friday.

"We arrested six people, including a member of the Sikh community, Buldev Singh," Azad Khan, a senior police official, told reporters in Peshawar, capital of the Khyber Pakhtunkhwa province.

"During initial investigations, Buldev Singh and other people acknowledged their involvement in the murder of Soran Singh."
