String of Robberies that are Occurring in our Neighborhood

Information passed to the board by a neighborhood member:
We got robbed of stainless cool box full of groceries that we leave out in our deck during the Winter season so we save some space in our fridge just this past holidays.  We have been living in this community over 9 years and never been robbed or heard of anyone being robbed.  I just thought this was one isolated incident and didn’t make much of it, didn’t report it to any authorities, but now our right next door neighbor just got robbed.  Their patio furniture has been stolen over the weekend.  Please alert the neighbors and provide some cautionary tips that we can follow so we don’t become repeat victims or worse someone getting hurt.
