A number of firearms and explosives have been found at a site in North Ockendon.
Police raided a derelict building and surrounding land in North Road yesterday.
The weapons recovered will be subject to expert forensic and ballistic examinations, but police provisionally believe them to be two AK47s rifles, a hand gun, a sawn-off shotgun, ammunition and a number of high explosive grenades.
