Police searching for a man thought to have access to a weapon near Looe have released an image of Derrel Weaver, aged 60, from Higher Widlake Farm, Widegates.
Mr Weaver is wanted in connection with the on going investigation which began following a domestic incident at the farm at around 9.30pm yesterday, Thursday, June 26.
If any member of the public sees Mr Weaver we would ask they did not approach him, but call 999 immediately.
A spokesman said: "It is currently unclear whether Mr Weaver may be armed, but this is a possibility. We would reassure Mr Weaver that police are not pre-judging any actions, but would like to speak to him as soon as possible.
"There remains a high police presence in the Widegates and wider Looe area which involves firearms officers and trained local officers."
Superintendent Jim Pearce said: “We would ask the public to be vigilant at what is obviously a disturbing time for local communities.
“If any member of the public sees Mr Weaver we would ask them to ring 999 and not to approach him.
“There is currently significant enquiries on going to locate Mr Weaver and this includes the chance he may be in possession of a firearm.
“There is currently no suggestion that Mr Weaver is any risk to members of the public, but we need to locate him as soon as possible.
“There is already extensive work on going to contact and speak to Mr Weaver by trained police co-ordinators and this also remains on going.
Supt Pearce added: “Police are aware of this and are doing everything possible to maintain the safety of the community, but we would ask all local people to be patient at what is obviously a disruptive time.
“There is a large number of police experts specifically trained for incidents like this currently involved in the operation.”
Trenode Church of England Primary School was closed in consultation with the head teacher earlier this morning (Friday 27 June).
