A Las Vegas official has been arrested following the murder of a veteran investigative journalist who reported on crime in the city.

Jeff German, 69, who worked for the Las Vegas Review-Journal, was found dead outside his home on Saturday morning.

On Wednesday evening, Clark County Public Administrator Robert Telles, 45, was arrested.

Telles, a Democrat, failed to win reelection following a series of stories written by German that exposed the turmoil in his office and claimed he had an affair with an employee. His home was searched by Las Vegas police hours before his arrest. 

By 6pm on Wednesday, police had returned to Telles's home in tactical gear and were surrounding the home while Telles remained inside. 

About 30 minutes later, he was wheeled out of the home on a stretcher and loaded into an ambulance, Las Vegas Review-Journal reported. 

Now DailyMail.com can reveal Telles had been railing against German for months – including in an angry series of messages on social media in which he accused him of rifling through his trash and writing 'lying smear pieces' about him.
