§ 156. Liability for a Prisoner on Work Release. No prisoner
participating in a work release program or whose place of confinement is
extended pursuant to this article shall be deemed an agent, employee or
involuntary servant of the department or the city while employed or
going to and from such employment or released from confinement pursuant
to this article; provided, however, that where a prisoner is employed
and paid by the city, his relationship to the city arising out of such
employment shall be determined in the same manner as if he were a free
person so employed.
