The incident took place outside Jandol police station in the mountainous Lower Dir district.
"A man was coming towards the police station, when police shouted to stop him he began running and blew himself up when police started firing," senior police official Akhtar Hayat Gandapur told AFP.
There were no other casualties or damage, he said.
Nobody immediately claimed responsibility for the attack, but Taliban militants have been carrying out similar bombings and suicide attacks in Peshawar.

now that is what we call an ideal suicide bomber
Bravo... a much needed story of the police doing their job
I wish all suicide bombers die this way!
