  In this paper, we consider $N$ non-intersecting Bessel paths starting at
$x=a\geq 0$, and conditioned to end at the origin $x=0$. We derive the explicit
formula of the distribution function for the maximum height. Depending on the
starting point $a>0$ or $a=0$, the distribution functions are also given in
terms of the Hankel determinants associated with the multiple discrete
orthogonal polynomials or discrete orthogonal polynomials, respectively.
