Four young residents of a North Philadelphia house who circulated petitions questioning police-surveillance cameras were rousted from their home Friday and detained 12 hours without charges while police searched their house.

Daniel Moffat, 28, a co-owner of the house, said police had no warrant when they entered. The house was examined by officials from several government agencies and then shuttered by the city's Department of Licenses and Inspections.

"This leaves me homeless, without access to things I need. My whole life is disrupted," Moffat said yesterday.
