Chimera - Season 1 Episode 2 Part Two

On his arrival in the sleepy Yorkshire town nearest the Jenner Clinic, the fiendish Government official, Hennessey, orders all police out of the area, and calls up an army of khaki-clad 'specialists' who throw a security web around the site. Highly placed and powerful, Hennessey conducts a cover-up; mutilated victims disappear en route to the mortuary; the press are officially gagged by a 'D' notice; and the regular police's mass-murder inquiry is abruptly cancelled without any explanation to the detective in charge.
