Both incidents happened during last week
If you have any information on either incident you're asked to get in touch with Carlow Garda station 059 9136620.
It follows a few cases this week where men pretending to be plumbers were let into people’s homes and then stole cash...
There were also a number of significant drugs seizures.
The warning comes as people still head off for mini-breaks before going back to work.
Locals are being advised to always lock your car, and not to leave items visible.
Sergeant Catherine O'Gorman says despite the arrest, they are still looking for people who saw anything to come forward.
