Detective Chief Inspector John Harris, said: “A man has tragically been killed and we are working hard to locate the offender.
“While the news that a man has been murdered, coupled with the police presence at the address will most likely cause some concern to residents, I want to reassure them that we believe this to be an isolated incident and there to be no wider threat to the community.
