BISMARCK, N.D. — Bismarck Police Department officials say they’re concerned about the city’s recent increase in serious crime.

The Bismarck Tribune ( ) reports that on Thursday, the department released a report analyzing crime and traffic in 2015.

Serious offenses in both personal and property crimes were up 25 percent from 2014 as the city saw an estimated population increase of 2.78 percent. The number of 2015 reports is above the five-year average.

The number of violent crime reports the department handled also increased by 25.76 percent from 2014 to 2015. Donlin noted that violent crime decreased by 8.5 percent in 2013 and by 10.9 percent in 2014. Still, the number of 2015 reports is above the five-year average.

Total calls for service increased by more than 9 percent, from over 34,000 in 2014 to over 37,000 in 2015.

“We’d like to even get those (assault numbers) much lower, especially in the domestic arena,” Police Chief Dan Donlin said.

Donlin says the Bismarck City Commission has approved the hiring of eight additional police officers in 2017 to prevent crime due to more visibility.

The police chief said the property crime category is where he hopes more officers on the streets will have an effect. However, he said people can help protect themselves by taking proactive steps, such as locking doors and vehicles.

Despite the recent increases, Donlin remains confident that Bismarck is a safe community.
