MADISON, Wis. (AP) — Madison police were called about shots fired at a park during an event commemorating the 20th anniversary of a fatal shooting.

Madison Police Chief Mike Koval wrote on his blog that officers were called to Elver Park on the west side of Madison late Saturday.

Koval says a large group had gathered in a small shelter to mark the anniversary of a shooting death when someone fired about three shots into the air.

The chief notes that dozens of children were in the area.

WMTV-TV reports hundreds of people were seen fleeing the park as officers arrived. A shell casing was found at the scene.

Police are still investigating.
