Police are appealing to the Greek community to help them find George Karakis, on the run since 1975.

The now 67-year-old is wanted for his alleged involvement in a serious sexual assault in 1975. He was last seen in Sydney in 1990, but police are unsure where he currently resides.

Born on February 9, 1947, he has brown eyes, black hair, an olive complexion and is of solid build.

Karakis is one of 20 fugitives police have named in operation ROAM, a national manhunt seeking information from the public to help them arrest criminals wanted for offences including murder, drug trafficking, robberies and sexual assault.

After one day of the operation, two of the twenty fugitives have been found and arrested.

Deputy Commissioner Tim Cartwright says the community plays an integral role in giving crucial clues to the whereabouts of these wanted people.

“There is a wealth of untapped community information out there; we need the eyes and ears of the community to help make Australia a safer place,” Commissioner Cartwright says.

Last year the same operation led to three arrests in the first 48 hours.

Crime Stoppers CEO, Sam Hunter says these fugitives cross state boarders and assume normal lives.

“They may be your mechanic, your neighbour, or catch the same train as you do each day,” he says.

“They have not just disappeared, the community holds to key to finding out where they are living.”

Crime Stoppers is a vital cog in helping police piece together the movements of criminals around the country.

In Victoria alone, Crime Stoppers receives 60,000 community contacts each year. Last year the service helped arrest more than 1200 offenders.
