Rochester police say one woman apparently slashed another during a fight at the Gantt R-Center on North Street.
Two city women got into a fight for unknown reasons, and family of one woman ran to the scene and joined in with a number of other people.
During the fight, a woman among those people pulled out a weapon and slashed one of the two women who were originally involved.
A security guard also suffered a hand injury.
Both were taken to Strong Hospital. The suspect drove off before police got there and is being sought.
