Managed to talk to the house owner just now and she confirmed the robbery happened on Thursday afternoon when nobody was around in the house.
The house do keep a dog but the barking did not deter the robbers.
The robbers went in through the main door middle glass panel. See picture below (red-highlighted).
The middle panel do not trigger the alarm.
The house was ransacked and some cash was taken.
The alarm system was not working at the time.
Police report was made and was informed the same robbers/operandi happened to Puteri 12 too during the last few days.
Hopefully this will be an impetus for all Puteri 11 owners to seriously look into the current security which is really below par.
