Months after the devastating Sydney Seige the Lindt Café in Martin Place has been vandalised, with rocks thrown through the windows the hostages once stood against.
A number of windows have large holes in them and a large rock was found near the glass doors of the café.
Channel 9 reports police believe the vandalism occurred this morning at 12:30am and after speaking to witnesses they are searching for one man.
The café only reopened in March after Man Haron Monis held a dozen people hostage on December 16.
An inquest into the siege is currently underway and the findings are expected to be delivered in early 2016.
