WATERBURY, Conn. (WTNH) — A 20-year-old man is in custody after threatening to bomb Saturday’s rally for Republican presidential candidate Donald Trump in Waterbury.

At about 12:45 p.m., the United States Secret Service contacted the Connecticut State Police after seeing a threat posted on Twitter threatening to “bomb” the rally for Trump.

According to state police, the Twitter post said, “Is someone going to bomb the Trump rally or am I going to have to?”

A second Twitter post warned the suspect’s friend to have his family members leave the rally so they wouldn’t be hurt. Detectives found that the Twitter posts came from the area of Ardsley Road in Waterbury from the account of Sean Taylor Morkys.

Morkys was located by State Police Counter Terrorism detectives, Waterbury police officers, and special agents from the United States Secret Service. He was taken into custody at about 5 p.m.

Morkys is charged with first-degree threatening, inciting injury to person or property, and second-degree breach of peace. The Waterbury man was released on a $25,000 bond and is due in Waterbury Superior Court on May 4.
