GRAND RAPIDS, MI - A Grand Rapids man is jailed on $500,000 bond after he allegedly tweeted threats of mass shootings and threats to Jews, police say.

David Lenio, 30, has faced similar accusations in the past after he allegedly posted tweets about killing Jewish religious leaders and shooting up schools while referencing the Sandy Hook killings.

Lenio was arraigned in Grand Rapids District Court on charges of use of a computer to commit a crime, a seven-year felony, and aggravated stalking, a five-year felony.

He also faces a misdemeanor of malicious use of a telecommunication device.

Police said his threats violated conditions of his release in Montana where he was arrested in 2015 for making similar threats.

As part of an agreement last year, prosecutors in Kalispell, Montana, deferred prosecution for two years if Lenio did not violate any local, state or federal laws. He allegedly wrote tweets about killing Jewish leaders and "shooting up a random school."

Lenio returned to Grand Rapids, into the custody of his family, after he entered into the deferred prosecution agreement.

Under conditions of his release, he was not to use social media, have access to firearms or have contact with any of the witnesses on the original charge.

Grand Rapids police say Lenio last month tweeted "threats of mass shootings and making threats of shooting persons of Jewish descent via his Twitter account while living in Grand Rapids."

Lenio faces a probable-cause hearing in Grand Rapids District Court on March 14 before Judge Christina Elmore.

As part of the agreement in the Montana case, prosecutors can refile a 10-year intimidation charge for violating conditions of his release.
