ST. AUGUSTINE BEACH, Fla. -

A 9-year-old boy was bitten by a shark in St. Augustine Beach on Sunday afternoon.  

The boy was with friends just south of the Ocean Trace Beach Ramp.  He was throwing a cast net into the water around noon when a shark bit him on the left leg.

The boy was treated on scene by St. Johns County Fire Rescue. His family took him to Flagler Hospital for stitches.

The shark was about 4 feet in length.

Authorities report this was the first shark bite in St. Johns County in 2013, although it's the third along Northeast Florida beaches since May.   There were a total of three reported in 2012, two in 2011 and four in 2010.

On Monday afternoon, a 17-year-old boy was bitten by shark in the waters off Ormond Beach.

Volusia County officials reported said the teen was bitten on his shoulder and taken to a hospital after the attack, which occurred around 12:30 p.m. near the intersection of State Road A1A and Granada.  The boy's condition was not immediately available.
