The party of Pakistan vote hopeful Imran Khan said Wednesday "a horde of 100 miscreants" attacked his home and beat his brother-in-law, as they accused the government of failing to provide security.
Islamabad police denied there had been any break-in at the hill-top villa of the cricket legend, a major contender in general elections next month, and blamed any disturbance on members of his own Pakistan Tehreek-e-Insaaf (PTI) party.
But PTI official Shireen Mazari demanded the immediate resignation of the interior minister, responsible for security in a caretaker administration guiding Pakistan towards May 11 polls, accusing him of imperilling Khan's life.
"The resultant attack on his house by a horde of 100 miscreants on Wednesday evening put his and his family's lives at risk while the police and local administration did not respond despite repeated calls," she said in a statement.
"Imran's brother-in-law was beaten and his female family members abused as his gate was broken and the hordes reached his house because no police protection was provided despite repeated demands," she added.
Islamabad police chief Bani Amin denied any break-in.
"No report has been registered. If anything has happened at Imran Khan's home, it may have been because of his workers who are demonstrating at his house for party tickets," he told AFP.
PTI members have been protesting outside Khan's home in the upmarket village of Bani Gala, just outside Islamabad, against what they call discrimination in how party candidates have been allotted various constituencies.
Insecurity, Taliban threats and bomb attacks have overshadowed much of the election campaign. Five deadly attacks targeting politicians or political parties have killed 24 people since April 11, according to an AFP tally.
The Pakistani Taliban have also directly threatened the three main secular parties in the outgoing government -- the Awami National Party, the Pakistan People's Party and the Muttahida Qaumi Movement.
