From the Garda Siochána:
BE VIGILANT! There have been numerous burglaries and attempts to burgle in the Terenure area (notably around Greenmount Road/Wasdale Grove and Park) earlier this week. The burglars knock on your door, usually late at night, and hide. Once the door opens they attempt to force their way in.
Please be very careful opening the door late at night. If you have a door chain, please keep it on the door before you open it. Please pass on this information to any elderly neighbours or friends in the area.
