FORT WORTH A former Denton High School teacher facing child porn charges won't get out of jail any time soon.

Greg Bogomol, 38, had a hearing in federal court on Wednesday. He is accused of using the Kik Messenger social media app to ask teenage boys for explicit pictures.

Attorneys for the Fort Worth man tried to get him released with a GPS tracking device, but a judge ruled that Bogomol must remain behind bars.

During the same hearing, Homeland Security agents testified that Bogomol admitted to having past complaints from students at schools where he taught.

A family tracked down by News 8 said there were 'red flags' as far back as early 2004.

The family accuses Bogomol of having an inappropriate relationship with their then-sixth grade student when he attended Burgin Elementary School in Arlington.

''One day [Bogomol] pulled his pants down. Another day he touched his privates with a ruler and asked if he knew how to use them,' the boy's father told News 8.

The family asked not to be identified.

An official police report was never filed, but the family said it reached an agreement with Arlington ISD to help send their child elsewhere.

The district said on Wednesday that Bogomol was only a teacher with them for a short time during the 2003-2004 school year, and that he resigned.

'We wanted to move on,' said the father. 'My son went from A's and B's to D's and F's.'

He said investigators reached out to the family just this week to find out more about the decade-old allegations.

'Homeland Security has already called my son, and talked with him about it,' the father said.

A federal complaint detailing the recent charges that landed Bogomol behind bars states the parents of a 15-year-old Louisiana boy reported he was solicited via cellphone to send nude photos and the teen complied. Investigators said the cellphone account led to Bogomol, who had allegedly portrayed himself online as a girl.
