Darren Lilly, 23, then was released on $500 cash bail. He did not enter a plea.
Sagadahoc County sheriff's deputies said that last month Lilly told two witnesses he planned to "shoot up" the Central Maine Community College campus in Auburn.
Investigators said that when they arrested Lilly he was in possession of several firearms -- including a semi-automatic gun in an instrument case.
Lilly's lawyer said the accusations have tarnished his client's reputation.
"We have a young man here who has a 40-hour-a-week job, who has no criminal history, who goes to work, minds his business, has never been in trouble," attorney Verne Paradie said.
Lilly is charged with terrorizing. There was no word on his next court appearance Tuesday.
