Less than 24 hours after news surfaced that he secretly photographed Newton elementary school students, former Newton teacher David Ettlinger has been indicted in Suffolk County on various assault charges. 

According to the Suffolk County District Attorney's Office, Ettlinger, 34, has been indicted on six counts of sexual assault charges. The charges include two counts each of assault and battery on a child under 14, posing a child in a state of nudity, and secretly photographing a nude or semi-nude person. 

Ettlinger is expected to be arraigned in Suffolk County Superior Court on Thursday, March 1. 

This is the second indictment for Ettlinger, who was held on $50,000 bail in Middlesex Superior Court earlier this month.

Ettlinger was initially arrested at his Brighton home on Jan. 17 and arraigned in Brighton District Court on multiple counts of possession of child pornography. He was arraigned on Jan. 18 in West Roxbury District Court for indecent assault and battery charges, and held on $100,000 bail. 

Authorities in Suffolk County allege that during the Jan. 17 raid of Ettlinger's apartment, officials found videos showing two children who Ettlinger allegedly assaulted and secretly filmed the abuse. Ettlinger had been charged with offenses against one of the victims; the second was identified during the course of the grand jury investigation, the DA's office said. 

The students were not Ettlinger's students, but are known to investigators, the DA's office said. 

On Feb. 8, Ettlinger was indicted in Middlesex County and subsequently arraigned in Middlesex Superior Court for charges related to a girl he allegedly assaulted while babysitting. 

At a pretrial conference in Brighton on Feb. 16, authorities said Ettlinger was likely to be indicted in Suffolk County as well. 

Ettlinger also faces federal charges out of the Western District of Louisiana for his involvement with the child pornography website "Dreamboard."

Last night, news broke that Ettlinger allegedly photographed some of his Newton students while working at Underwood Elementary School. The photographs were reportedly non-pornographic and Ettlinger will therefore not face criminal charges for the pictures. 

Ettlinger taught in the Newton Public Schools for 12 years, at both Peirce and Underwood Elementary. He resigned from his teaching position on Jan. 31.
