Khyber-Pakhtunkhwa Chief Minister Pervez Khattak had visited slain chemistry professor Hamid Hussain's residence in Swabi district to express condolence to his family members over his death.
The family members asked Khattak to quit if he could not provide security.
Hussain, 34, was killed in the Wednesday terror attack on Bacha Khan University in Charsadda while trying to protect students using his licensed pistol against armed Taliban militants who stormed the university, and has been hailed as a "martyr".
