TRENTON, N.C. (WITN) -- A teacher's assistant and assistant football coach is now under arrest after the State Bureau of Investigation was brought in to look into allegations at Jones Senior High School.

Dammion Martin of Maysville has been charged with two counts each of 2nd degree sexual offense, 2nd degree sexual activity by school personnel, and crimes against nature.

The 34-year-old turned himself into the SBI in Jacksonville this morning. He's now en route to the Onslow County jail under a $100,000 bond.

The school system says Martin is no longer employed by them.

A month and a half ago, district attorney Dewey Hudson asked for the SBI investigation after the victim's father contacted state authorities and said nothing had been done in the case.

The D.A. also asked the SBI to look into whether Jones County officials properly handled the allegations.

Hudson says there are actually two victims. He says one of the offenses happened last November and another during the spring semester of 2006.

Both involved female students at Jones Senior High School and happened at the school.

Hudson says he found no evidence that the Jones County Sheriff's Department did any thing unethical, or that they tried to cover up what happened. The district attorney says he accepts the sheriff's explanation that there was a backlog of cases. He says Sheriff John Hall will now take steps to take to place a school resource officer at the high school.

Allegations were also made that the school system failed to notify law enforcement of the incident last November. Hudson says after looking into this matter it appears the school system did take some steps to notify deputies about last year's case after it happened.

But the D.A. says there are no records that show the school system notified law enforcement about the 2006 case. Not notifying law enforcement of a possible crime on school property to a class 3 misdemeanor, but Hudson says the statute of limitations has expired in that case.

The D.A. says because law enforcement officers were not notified in 2006, deputies did not investigate that situation and "were unable to take action to attempt to protect that student or any others who may have been in harms way."
