Scotland's elite crime fighting agency is capturing more "captains of crime" than ever before, its chief said.
The Scottish Crime and Drug Enforcement Agency (SCDEA) said 2009-10 will be seen as a watershed year in the country's battle against serious organised crime.
The agency reported 136 arrests in the last year, including the snaring of 67 serious offenders known as "level 3" criminals.
They include major players in the drugs trade such as Paul Ward and Shaun McKinnon, ringleaders of a dealing network who were jailed in Edinburgh in April following Operation Venom.
Police also targeted assistants to criminal gangs, with the arrest of an electrics expert employed to sweep premises for police recording devices.
A delivery man was also charged with smuggling mobile phones into Perth prison in milk cartons.
The SCDEA annual report published today revealed that around £22 million-worth of criminal assets were identified for seizure under the Proceeds of Crime Act, almost three times the annual target of £8.5 million.
Class A drugs with an estimated street value of more than £21 million were also seized, although the 105 kilograms recovered represented less than half the 300 kilogram target.
The organisation said 51 kilograms of high-purity cocaine seized abroad would have been bulked to more than eight times the amount if the drugs had reached Scotland.
Deputy chief constable Gordon Meldrum, SCDEA director general, said: "Yesterday we were primarily getting the foot soldiers of organised crime; important in providing communities with respite but less effective in disrupting a network's operations. Today it's the captains and lieutenants.
"We are now very firmly focused on taking down the generals. For them, that's what tomorrow is going to bring.
"Turning intelligence into action has helped us to target the right people with the right resources where we can hit serious organised crime where it hurts most.
"Often that will mean high-level arrests and the seizure of drugs. It is also demonstrated by the everyday disruption that a whole range of organisations inside and outside law enforcement are now causing to these criminals, from routine vehicle checks to the confiscation of their assets."
The director told SCDEA members in the annual report: "The year 2009-10 may come to be looked upon as a watershed in this country's continuing fight against serious organised crime."
Justice Secretary Kenny MacAskill said: "The arrest of more serious organised criminals than ever before sends out a clear message to the gangsters: the police know who you are, they know what you're up to and they are determined to bring you to justice."
