Stolen bikes is a "major issue" in the Rathmines/Rathgar area, said Independent councillor Ruairi McGinley.
"The issue of stolen bikes appears to be a major issue with some people having multiples instances of bikes being stolen," said the Dublin city councillor.
He added that there have been recent reports of many cars being stolen in the Rathgar area. The thefts appear to be "to order".
Robberies from shops are also a growing issue.
