  All identical particles are inherently correlated from the outset, regardless
of how far apart their creation took place. In this paper, this fact is used
for extraction of entanglement from independent particles unaffected by any
interactions. Specifically, we are concerned with operational schemes for
generation of all tripartite entangled states, essentially the GHZ state and
the W state, which prevent the particles from touching one another over the
entire evolution. The protocols discussed in the paper require only three
particles in linear optical setups with equal efficiency for boson, fermion or
anyon statistics. Within this framework indistinguishability of particles
presents itself as a useful resource of entanglement accessible for practical
applications.
