Properties across Greater Manchester were raided as part of a crackdown on money laundering.
Greater Manchester Police's Economic Unit Crime made nine arrests as a number of warrants were executed simultaneously as part of a money laundering operation.
The warrants were conducted by the Economic Crime Unit alongside the Tactical Aid Unit, Serious Organised Crime Group and the North West Regional Organised Crime Unit (NWROCU).
Nine men between the ages of 36 and 63 were arrested on suspicion of money laundering, fraud and organised immigration crime offences on Thursday.
Police say the arrests are the "culmination of a lengthy investigation into individuals suspected of being involved in high level money laundering offences spanning at least three years".
The group are suspected to have profited from organised immigration crime in Manchester by producing fake identities and businesses in an attempt to money launder their criminal profits.
A total of 12 properties were searched and items of jewellery, watches and vehicles estimated to be worth in excess of £180,000 have been seized along with £50,000 in cash.

Detective Superintendent Andy Buckthorpe from the Economic Crime Unit, said: “As a unit we have worked extremely hard to get to a point where we can execute these warrants.
“We remain robust in our approach to tackling money laundering, and the action today is part of longstanding approach to ensuring that we are tackling economic crime head on using all resources available to us.
“Today’s action will definitely cause disruption among criminal networks within Greater Manchester as they wake up and hear this news, and hopefully this action today will be reassuring to those members of the public who are rightly concerned by money laundering in our communities.
“As a unit, our focus will always remain on dismantling organised criminal finances and we will work with this same momentum, seizing cash and assets from those who wish to harm our communities and we are asking the public to remain vigilant and if you see, or suspect something is wrong, tell us, and we can do something about it."
