Police uncovered what they call a "prison room" in Texas where at least four victims were being held against their will.

Officers responded to the Houston home at 8:30 a.m. after a tip that four men, ages 79, 54, 74 and about 65 were being held captive in the garage, KTRK reports. When they arrived, the front door was nailed shut. Inside they found a trash-ridden room with no beds. The four victims were inside.

One of the victims says he's been there for about 10 years, according to CNN. Three of the men couldn't walk and were transported to a nearby hospital.

Three women and a suspect live in the house, and one person was taken into custody. It wasn't immediately clear whether that person would face charges.

Details about the victims and their captivity were still hazy at press time. Police told some news sources that the men may have been homeless, and were lured to the house with beer and cigarettes in exchange for their Social Securty and Veteran's Administration checks, FOX 4 reports.
