WATERTOWN, N.Y. (AP) — A 31-year-old man has been charged in a weekend shooting at a northern New York nightclub where five people were wounded, four of them soldiers from Fort Drum.

Police in the city of Watertown say the shooting occurred around 1:20 a.m. Saturday in the fenced-in outdoor area at Club Rio. Officials say four people hit by gunfire were taken to a local hospital where they were treated and released.

A fifth person was taken to a Syracuse hospital for treatment and then released.

Police say Monday they're still trying to determine what led to the shooting.

Julio Landron-Sanchez was arraigned Saturday with assault and is being held on $50,000 bail. Prosecutors didn't know if he has a lawyer yet.

Officials say four of the injured are assigned to nearby Fort Drum, home of the Army's 10th Mountain Division.
