A Wisconsin police chief says a dashcam video appears to show that officers who fatally shot an armed hostage in December gave no warning before they fired outside of a motorcycle shop.

Neenah Police Chief Kevin Wilkinson commented Thursday on the video, which was obtained and published online by the USA Today Network . It appears to show Michael Funk wasn't warned Dec. 5 as he ran from Eagle Nation Cycles shop, where hostages were being held.

Neenah police had said shortly afterward that Funk ignored orders to drop his gun.

Wilkinson told The Associated Press that the initial information about Funk ignoring orders was from witness interviews, but that the nearly 5-minute video shows there appear to have been no warnings.

Wilkinson also said officers are not required to give warnings.
