The defined group of offences relates, but is not exhaustive to, death by dangerous driving, serious assault with intent to cause serious harm, attempted murder and murder.
The number of crimes have been reducing month-on-month, 32 crimes in July, 23 in August and 15 in September.
A report states: “A review of the crimes show domestic abuse, night-time economy and organised crime groups are the prevalent causation factors of the crimes committed.
“Over 71 per cent of the crimes are under the category of assault with intent to cause serious harm and over half of the offences being domestic related.
“During the same period there were 87 investigations whereby use or possession of a knife was involved, either as a weapon or carried during an offence.
“This is a slight decrease from the previous quarter.
“Of the 87 investigations, 33 per cent were attributed to possession of a weapon with the remaining being used in the commission of the offence.”
