Connecticut State Police arrested a 20-year-old man who they say threatened to bomb a political rally for Donald Trump.

Secret Service agents contacted the state police on Saturday regarding a threat posted on Twitter that made reference to detonating a bomb at a Trump rally in Waterbury, authorities said.

"Is someone going to bomb the trump rally or am I going to have to?" the post read, according to police.

A second Twitter posting warned friends and family to leave the rally to avoid harm, police said.

Investigators traced the posts to an account used by Sean Morkys of Waterbury.

After interviewing Morkys, investigators determined he posed no threat to the public.

Nevertheless, they charged Morkys with first-degree threatening, inciting injury to person or property and second-degree breach of peace, authorities said.

He was being held in lieu of $25,000 bond.
