(CNN) Two people have been bitten by sharks off the coast of North Carolina in the past 14 days and a third person is believed to be a shark bite victim during that time period, officials said.

On Sunday, an 8-year-old boy was bitten by what's "believed to be a shark," according to village manager of Bald Head Island Chris McCall.

McCall says the child suffered non-life threatening injuries in the incident off Bald Head Island's South Beach.

The boy had puncture wounds on his leg and was transported off the island to receive medical treatment, McCall said.

McCall said authorities don't know what type of shark was involved in the attack.
