An officer asleep on the job inspired Mr Brunstrom to join the force
The chief constable of North Wales Police Richard Brunstrom has announced that he will retire from the force in July.
His retirement concludes more than eight years as leader of the force and 30 years with the policing service.
Last year, Mr Brunstrom had announced that he expected to retire by Christmas 2009 but later said the person who announced his departure was "mistaken".
Mr Brunstrom has faced controversy throughout his time as chief constable.
Ian Roberts, chair of the North Wales Police Authority, said they were sorry to learn of Mr Brunstrom's intention to retire.
"I would like to pay tribute to his unflagging energy and commitment to making North wales a better and safer place," he said.
"Under his leadership north Wales has become one of the best performing forces in the UK.

He was dubbed the "Mad Mullah of the Traffic Taliban" because of his strong views against speeding.
In 2007, Mr Brunstrom was criticised for showing pictures of a decapitated biker at a private briefing without the permission of the man's family.
He admitted later he had made a "stupid" mistake but then partly blamed the media for reporting what he had done.
In September 2007, he also subjected himself to a 50,000 volt taser to test the effects.
In December he reportedly broke into his own Colwyn Bay headquarters to test security, but it recently emerged he may have had a faulty key fob.
He is also known for his support for the decriminalisation of heroin.
Mr Brunstrom originally announced his intention to retire in a programme broadcast on BBC Radio Wales in August 2008.
In it he said he wanted to buy a boat and sail with his wife when his contract ended.
But in an interview with a local paper later that month, he said the person who announced his departure was "mistaken".
