"Whilst it is too early to speculate on what the motive behind this attack was I am confident, based on the information currently available to me, that it is not terrorist related.
"Local officers and specialist detectives are at the scene and will remain there for many hours to come.
"Specially trained family liaison officers will be deployed to support the family; we request that their privacy is respected at this very difficult time."
