The nine suspects indicted in the shooting of Red Sox great David Ortiz will remain behind bars for at least a year while the investigation continues, according to a report.

The suspects were led into a Dominican courtroom Friday wearing vests and helmets to protect them from an angry mob upset about the attack on the local sports hero, the Boston Globe reported.

A judge cited the case’s complexity for the unusual decision to order a lengthy jail term before trial.

Prosecutors announced Friday that they expect to provide a detailed account of the shooting and identify the masterminds as early as next week, the paper reported.

Officials want to keep the alleged hit men separated and will divide them among four different prisons, it said.

The Red Sox slugger was at an outdoor bar in his hometown of Santo Domingo Sunday when a man jumped off a motorcycle and shot him from behind. He is in stable condition at a Boston hospital, where he underwent a second surgery Monday.
