Police in Pakistan have arrested a man accused of insulting Islam's holy book after being alerted that a mob wanted to lynch him. They say the man was arrested Tuesday on the outskirts of Peshawar, the capital of deeply conservative Khyber Pakhtunkhwa province. Video posted on social media showed hundreds of people blocking a road near a police station and demanding the man be handed over to them. Police say the man allegedly made derogatory remarks about the Quran during a heated argument with his brother at the family's home.
