ORANGE CITY, Iowa | A former teacher charged with having sexual contact with more than a dozen children has been released from custody.

Curtis Van Dam posted 10 percent of his $150,000 bond Tuesday and bonded out of the Sioux County Jail. The bond was secured through Lederman Bail Bonds.

Van Dam, 36, of Sioux Center, Iowa, has pleaded not guilty in Sioux County District Court to 146 charges related to sexual contact with at least 13 children between August 2014 and this past October. He is scheduled to stand trial March 6.

As part of his bond release, Van Dam promises to appear for future court hearings.

District Judge Patrick Tott on Monday had continued Van Dam's bond at $150,000. As part of the order, Tott said that if Van Dam bonded out of jail he must wear an electronic monitoring device on his ankle and be supervised by the Department of Correctional Services.

Other conditions of release include:

-- He must not go within 100 yards of a child care or educational facility.

-- He may have no contact with any child under age 15 except for his own children or the children of family members if supervised by another adult.

-- He may not leave Iowa without permission of his pretrial supervision officer. He may travel to Spirit Lake, Iowa, to meet with his attorney, Edward Bjornstad.

Van Dam was arrested Oct. 23 after a complaint was filed against him for inappropriate contact with a student. Administrators at Sioux Center Christian School removed Van Dam, who taught fifth grade, from the school after the complaint was filed. As Sioux Center police investigated the complaint, they filed additional charges related to incidents with other children, and Van Dam was fired.

Police have said the incidents took place at various locations, including the school, where Van Dam taught for nine years. Court documents and police have not revealed the gender of the alleged victims.

Some or all of the children were under age 12 or 13. Van Dam is accused of sexually abusing or having inappropriate contact with some of the children on at least 24 separate occasions over several months.

Van Dam is accused of having children fully or partially undress in front of him, permitting children to touch his genitals and exposing himself to some of the children.
