RALEIGH, N.C. -- State authorities are investigating after a homeless North Carolina man says he was brutally beaten by law officers while he was unarmed and crossing a street.

• Kyron Hinton claims he was beaten by police April 4.
• Hinton is charged with three misdemeanors.
• The SBI is investigating.

Twenty-nine-year-old Kyron Dwain Hinton tells media outlets he suffered a fractured eye socket and broken nose and was bitten more than 20 times by a K9 during an April 4 encounter with Raleigh police officers and Wake County sheriff's deputies. 

Hinton says he didn't know why he was being arrested or why officers hit him.

The Wake County Sheriff's Office charged Hinton with three misdemeanors including resisting a public officer. Arrest warrants accuse him of implying he had a gun and hitting a sheriff's office K9.

Hinton recalls a different scene.

"Really, as a human being, mauled by a dog, beat by the people that's protecting and serving. I don't have a gun, I don't have drugs on me, and I'm walking down the street. I mean, that's just inhumane," said Hinton.

Wake County District Attorney Lorrin Freeman says the State Bureau of Investigation is probing the incident. The result of the investigation will dictate how Hinton's legal team proceeds.

Hinton is due in court on May 14.
