EDMONTON -- Graffiti was discovered this week in Constable Ezio Faraone Park in Edmonton.

A statue and plaques honouring fallen Edmonton police officers Const. Faraone and Const. William L. Nixon were marked with black and white spray paint.

Const. Faraone was killed while in pursuit of two bank robbers three decades ago.

A service was held in his memory in June, 30 years after his death.

Alberta Premier Jason Kenney condemned the vandalism on Twitter. 

"It is despicable to dishonour the memory of those who gave their lives in the defence of our community," Kenney wrote. 

The Edmonton Police Service is investigating and believe the vandalism happened overnight between Sept. 2 and the morning of Sept. 3. 

Anyone with information or dashcam video from that night is asked to contact police using the non-emergency line at 780-423-4567 or by dialing #377 from a cell phone. 

The Faraone statue has been targeted by vandals before. "ACAB," an acronym meaning "all cops are bast****," was painted on the monument in May and July of this year. 

An anarchy symbol was also spray painted on the plinth in 2012, and 2003.
