DOVER, Del. (AP) — Department of Correction officials say more than a dozen Delaware inmates charged in a fatal prison riot last year staged a brief hunger strike this week.

Officials say 14 inmates at Sussex Correctional Institute in Georgetown began refusing meals at breakfast on Monday.

Department spokeswoman Jayme Gravell said in an email Tuesday evening that the demonstration had ended, and that the all of the involved inmates had eaten and taken their medication as prescribed.

Officials say all 14 inmates were involved in the February 2017 riot at James T. Vaughn Correctional Center in Smyrna, during which a prison guard was killed and three other staffers were taken hostage.
