Parkland school shooting suspect Nikolas Cruz was involved in an incident inside the Broward County Jail, where he is awaiting trial for allegedly killing 17 people in February.

Officials with the Broward Sheriff’s Office confirmed to NBC 6 that Cruz attacked a detention deputy inside the facility early Wednesday morning. The deputy involved was hurt, but the extent of his injuries are unknown at this time.

According to BSO jail records, Cruz faces three preliminary charges that include aggravated assault and battery on an officer as well as use of a chemical or electrical weapon on an officer. All are felony charges. The charges are listed on the jail's website in addition to the 34 charges he faces for the shooting at Marjory Stoneman Douglas.

Cruz's attorneys had no immediate comment.

The incident comes at the same time as the MSD commission is meeting in Sunrise, with Broward schools superintendent Robert Runcie, Sheriff Scott Israel and Scot Peterson — the school resource officer who has been criticized for his response during the shooting — scheduled to speak.

On Feb. 14, Cruz allegedly entered Marjory Stoneman Douglas High School, where he was once a student, and opened fire, killing 14 students and three staff members before being arrested shortly after. He entered a plea of not guilty after prosecutors announced they would seek the death penalty in the case.
