Tehreek-e-Taliban Pakistan commander Maulvi Faqir Muhammad was arrested during a search operation in eastern Afghanistan.
Pakistan authorities have long demanded that Kabul take action against Pakistani insurgents who take refuge in areas of eastern Afghanistan just over the border. Kabul, in turn, says the insurgency in Afghanistan draws sustenance from sanctuaries in Pakistan.
Faqir was captured during a raid in Nangarhar province by members of the Afghan intelligence agency, the National Directorate of Security (NDS), and Afghan police officers, according to officials from NDS and the Afghan interior ministry.
Faqir has a tumultuous past with the Pakistani Taliban and last year was sacked as commander of the northern Bajaur region, after telling Pakistani media the TTP were holding peace talks with the government.
The TTP denied his claim and replaced him with another commander, Mullah Dadullah. After Dadullah was killed in a Nato air strike in Afghanistan in August last year, Mohammad resumed his role.
Mohammad was responsible for several attacks against Pakistani forces and was known for his strict implementation of Islamic law in Bajaur.
