ANTIOCH — A homeless camp set up by a transient here proved to be a unique one — until police put an end to it.

Police did not identify or release the gender of the person who set up a home on the roof of the Amtrak train station at 100 L St. That person may have stayed there awhile if a bystander hadn’t noticed somebody lowering a bike from the roof sometime early after sunrise on March 8.

When police were called to the scene, Officer Tom Lenderman found a roof-top camp that was deemed “unsafe,” according to the Antioch Police Department’s Facebook page.

Police then immediately broke up the camp.

“Homelessness is not a crime,” the department wrote in a statement on its Facebook page. “We try to get our homeless citizens into services so they can have a stable environment.”

Police did not say whether the person was cited for trespassing.
