  In this paper, we study an integrable Camassa-Holm (CH) type equation with
quadratic nonlinearity. The CH type equation is shown integrable through a Lax
pair, and particularly the equation is found to possess a new kind of peaked
soliton (peakon) solution - called {\sf rogue peakon}, that is given in a
rational form with some logarithmic function, but not a regular traveling wave.
We also provide multi-rogue peakon solutions. Furthermore, we discuss the local
well-posedness of the solution in the Besov space $B_{p,r}^{s}$ with $1\leq
p,r\leq\infty$, $s>\max \left\{1+1/p,3/2\right\}$ or $B_{2,1}^{3/2}$, and then
prove the ill-posedness of the solution in $B_{2,\infty}^{3/2}$. Moreover, we
establish the global existence and blow-up phenomenon of the solution, which
is, if $m_0(x)=u_0-u_{0xx}\geq(\not\equiv) 0$, then the corresponding solution
exists globally, meanwhile, if $m_0(x)\leq(\not\equiv) 0$, then the
corresponding solution blows up in a finite time.
