IOWA CITY, Iowa (AP) – Inmates at a Rockwell City prison were found in possession of pills, cellphones and a hammer in a series of incidents last month raising questions about security. Records released to The Associated Press show one inmate was trying to break into the woodshop at the North Central Correctional Facility. He had pliers, a putty knife and a hammer. The inmate later revealed a hidden compartment containing a cellphone and iPod.

Another inmate had a cellphone he used to make calls outside the prison and for Facebook. A third inmate said cellphones – considered dangerous contraband under Iowa policy – were for sale inside the prison for $120.

Officers discovered 400 pills that initially were suspected to contain cocaine and Demerol. Later testing came up negative for narcotics.
