A bomb threat at Metropolitan Detention Center in Sunset Park Monday morning forced many to evacuate, including lawyers and visitors frustrated by other issues at the jail.

The bomb threat lasted a few hours before the NYPD determined the building was safe. But hours later, a large police presence remained with armed guards blocking the entrance.

News 12 spoke to a woman who came from Manhattan to visit her husband, only to be turned away with no word for when her visitation would happen.

Those advocating for fair treatment of the inmates say lawyers were also turned away from seeing clients.

This all comes after an intense three days of protests between the detention center, family members and advocates. The facility had been operating with limited heat, hot water, electricity, medication and hot meals for a week following an electrical fire.

Power and heat was restored Sunday evening, but now families want to make sure their loved ones are doing well.

Legal Aid Society has filed a lawsuit on behalf of the inmates at Metropolitan Detention Center. There will be a court hearing on the center's conditions Tuesday morning.
