Distribution of the minimum of the squared Euclidean norm of a $N(\mu,\Sigma)$ random variable

Suppose that $X^n := \{x_1, x_2, \ldots, x_n\}$ is a sample of $n$ i.i.d $p$-dimensional points, where $X \sim N(\mu, \Sigma)$. What is known about the distribution of $\min_{x_i \in X^n} \|x_i\|^2_2$?...
