  The boundary state corresponding to the D$p$-brane with a transverse rotation
in the presence of the Kalb-Ramond and tachyon background fields and a $U(1)$
internal field will be constructed. We shall investigate effects of the open
string tachyon condensation on this brane via its boundary state. We
demonstrate that the background fields and transverse rotation cannot protect
the brane against the collapse. Our calculations are in the context of the
bosonic string theory.
