BANGOR, Maine — A Dexter man pleaded not guilty Friday at the Penobscot Judicial Center to sex charges involving a 3-year-old girl.

Dustin Stevens, 25, was indicted Wednesday by the Penobscot County grand jury on one count each of gross sexual assault and unlawful sexual contact.

District Court Judge Gregory Campbell set bail at $5,000, the amount requested by the Penobscot County district attorney’s office.

Through Bangor attorney Benjamin Fowler, who represented Stevens at Friday’s arraignment, Stevens said he could not afford to post any bail because he has not worked in more than a year. Fowler asked the judge to set an unsecured bail.

“Given the seriousness of the charge, $5,000 is very reasonable,” Campbell said.

Stevens remained at the Penobscot County Jail Friday evening unable to make bail.

Bail conditions include no contact with the victim or her immediate family and no contact with children under the age of 18.

Stevens’ next court appearance was set for March 12.

Michael Roberts, deputy district attorney for Penobscot County, declined Thursday to say what the relationship between Stevens and the victim was. The alleged conduct took place in October 2011 and was reported to the district attorney’s office by the Department of Health and Human Services, he said.

The prosecutor also declined to describe the alleged sexual contact but said intercourse was not involved.

The victim now is four, Roberts said Thursday.

If convicted, Stevens could be sentenced to up to life in prison on the gross sexual assault charge, a Class A crime, Roberts said. The Dexter man also could be required to register as a sex offender for life.
