( CNN ) -- Australian police arrested a 23-year-old man in Melbourne on Tuesday on suspicion of funding a U.S. citizen who went to fight in Syria .

His arrest , in a joint operation by the Australian Federal Police and Melbourne Joint Counter Terrorism Team , came after searches at seven addresses in Melbourne suburbs . Police said there was no known link to an incident last week in which a teenage terror suspect , Numan Haider , was shot dead outside a police station in Endeavour Hills , Melbourne , after he stabbed two police officers .

In this case we will allege that the man was funding someone from the US . However who is being funded makes no difference , '' Gaughan said . `` Providing funding is equally criminal as actually traveling to participate and we will use all our resources to cut off the supply of funds to terrorists .
