A suspect is in custody following a stabbing at a Siesta Key nightclub late last week. Police say Thursday night, two men were fighting at a club on Ocean Boulevard. After the bar closed, the suspect, now identified as 24-year-old Andreas Leonardo Montilla-Monsalve, stabbed the person he had been fighting earlier in the back. Surveillance video led to the arrest. Montilla-Monsalve was charged with Aggravated Battery with a Deadly Weapon.
