Two Secret Harbour homes were targets of a Christmas present thief overnight.
Around 10pm on Friday, police were called to a home on Warrender Heights.
Personal items were stolen including kids Christmas presents.
Police were then called out to a home on La Spezia Drive around 7.30am after the homeowner noticed all the gifts from under her Christmas tree were gone.
"To who ever broke into our home in the early hours of the morning and stole our entire lot of gifts I hope your proud," she posted on a community Facebook page.
"I’m a single grandparent raising 4 of my grandbabies, you also left our gates open and luckily someone stopped at 5.30 and knocked on my door to let me know our gates were open and our dogs were out one who is blind, I am totally heart broken."
Mandurah Detectives are investigating both burglaries.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
