Police are searching for a Canberra man who ran from the ACT Supreme Court during proceedings yesterday afternoon.

ACT police have issued a warrant for the arrest of Craig Joseph Stevens, 37, who was on trial in the ACT Supreme Court.

It is understood the jury briefly left the courtroom during proceedings.

Stevens was ordered to remain in the Supreme Court building, but he bolted from the court while the jury was out.

Despite being chased by security, he escaped into Civic, and authorities have been unable to track him down.

His family took to Facebook, appealing to Stevens, asking him to let them know of his whereabouts.

"Craig you are stressing your family out please contact your dad this is not helping," one relative wrote.

Police confirmed Stevens had not been located on Saturday morning, and officers are continuing their search.
