Des Moines police say three officers involved in two separate crashes have been found at fault and disciplined.

The Des Moines Register reported Tuesday the first crash happened April 7 at a four-way stop sign. In that case, officers Phil Terrones and Brandon Holtan were headed to a shots-fired report. Neither fully stopped at the signs and collided.

The other crash came April 27 when officer Mitchell Cameron was responding to assist another officer and ran a red light. Police say he hit another vehicle broadside.

Police say the officers have been disciplined but they declined to be specific because the matter is a personnel issue.

In general, Des Moines police Sgt. Jason Halifax say crashes of patrol cars in which officers are at fault usually result in suspensions.
