**A pro-Taliban cleric arrested in Pakistan on Sunday will be interrogated by a team of police and intelligence agencies, officials say.**Sufi Mohammad was arrested in the city of Peshawar in Pakistan’s North West Frontier Province (NWFP) after being warned not to hold meetings there.
Officials said the cleric had been detained for encouraging terrorism.
He negotiated a peace deal in February, widely seen as allowing the Taliban to take control of Pakistan’s Swat valley.
Under the terms of the deal militants were allowed to impose Sharia law in the district in exchange for an end to two years of fighting.
However the deal later collapsed when Taliban fighters failed to disarm and moved into neighbouring districts.
Joint investigation
Officials say the police as well as security agencies will be involved in the interrogation and investigation of the cleric.
The Pakistani government has accused him of undermining its efforts to restore peace in the north-west Malakand region, and says he will be tried for his crimes.
Sufi Mohammad is the founder of a banned militant group, Tehrik Nizam Shariat Mohammadi (TNSM).
He is also the father-in-law of the Taliban leader in the Swat valley, Maulana Fazlullah.
Sufi Mohammad, who led thousands of tribesmen to fight American troops in Afghanistan, had been held in prison until April 2008.
He was released by NWFP government after signing an accord whereby he was to negotiate peace with militants in the Swat valley.
The BBC’s M Ilyas Khan in Islamabad says the government believes Sufi Mohammad threw his weight behind the militants, refusing to chastise them for their actions.
Many believe his TNSM group served as the political face of Swat militants.
