Upon arrival, officers interviewed witnesses, who reported a male entered the establishment, stole multiple bottles of liquor from a shelf and while attempting to flee, forced a 59-year-old victim to the ground and struck her.
The victim suffered non-life threatening injuries, police said.
A subsequent investigation led to the arrest of James R Shipley, 21, of 207 W. Fifth St. Apt. 1, Oswego.
He was charged with Robbery in the second degree (a class C felony) and Assault in the third degree (a class A Misdemeanor).
Shipley was being held at the Oswego City Police Department pending arraignment.
