DELAWARE, Ohio (WTVN) -- A 57-year old Columbus man has been indicted for unlawful sexual conduct with a teen girl at Highbanks Metro Park.

Investigators say Scott Spencer met the 14-year old girl online. A park ranger found Spencer alone with the girl on August 15.

“Parents need to be vigilant in their efforts to find out what their children are doing online and who they may be corresponding with,” said Delaware County Prosecutor Carol O’Brien.

Spencer is charged with 2 counts of unlawful sexual conduct with a minor. Investigators say the incident at Highbanks was the second time the two had met up for sex.

An arraignment hasn't been set.

Spencer had been fired from his job at ODOT for viewing pornographic websites at work. He had also been punished for leaving "unwelcomed" voicemail for a female co-worker.

He was a media liaison with the Ohio House Republican Caucus in the 1980s and 1990s.
