Update (4:11 p.m. Eastern): CNN is now reporting that police found eight people in the Houston home, all men between the ages of 50 and 80.

Police found that four elderly men had been kept captive in a north Houston home in poor and dirty conditions, according to Houston local TV station KTRK.

Police arrived at a home on the 8600 block of White Castle Lane to find the door had been nailed shut and that several people had been kept in the garage, with one victim saying he had been held captive in the home for more than 10 years. Police described the conditions as "prison"-like, with no bed or chairs in the room where the men were being held.

The four unnamed victims, ages 79, 54, 74 and about 65, were held against their will. Police found that three of the men were unable to walk and were transported to LBJ Hospital nearby. One man reportedly said he had been held for about six months and had no desire to leave.

"One of them seemed to think he was picked up off the street and brought here," HPD Sgt. JW McCoy told KTRK. "In exchange for beer and cigarettess and a place to stay, he had to turn over his Social Security check."

CNN reported that one man had been detained for questioning.
