The soldier arrested in Jerusalem on Saturday for posting death threats on a gay Internet forum was remanded for a further three days in custody on Sunday afternoon.
The suspect, 20, serves in the Nahal Haredi battalion.
"He threatened to attack the gay community. He wrote things like 'get ready for another hit. It's coming. Don't say you weren't warned,'" Jerusalem Police spokesman Shmulik Ben-Ruby told The Jerusalem Post.
The threats were posted on the Ga'ava (Pride) Internet forum which serves the gay and lesbian community.
