"Police can confirm the man and woman were known to each other and we would like to reassure the community that we are not seeking anyone else in relation the mans murder.

"Police have been at the scene since early hours this morning conducting a scene examination and will continue to speak to witnesses over the coming day.

"Police expect to remain at the scene over the next two days.
