Three out of four burglaries are not detected, according to figures released by the Central Statistics Office.

The figures for the five years from 2006 to 2010 show that less than 4% of all such cases reported involved aggravated burglary.

The figures show that 53% of all burglary cases resulted in a conviction in 2010. 

The report also found that gardaí detected more than 80% of homicide offences and in one year (2007) the detection rate was as high as 90%.

The detection rate for drugs offences was also over 90%. Men under the age of 25 represented 46.5% of all those convicted for such offences.

The CSO figures also show substantial increases in recorded sexual offences, kidnapping, drugs and weapons and explosives offences.

These figures, which provide a broad overview of recorded and detected crime, show significant increases in serious and organised crime over the five years from 2006 to 2010.

Drugs offences were up 40%, gun and explosives crime up 30%, robbery extortion and hijacking up 28% and kidnapping increased 59%.

Recorded sexual offences increased by 66% but there were decreases in the incidence of homicide, public order and road traffic offences over the five years.

However, four out of every five crimes of damage to property and the environment and three out of every four burglaries were not detected.
