Hunt for killer 'Wolf' - bad bikie lying low

His arms are said to be covered in scars, distinctive Hells Angels tattoos adorn his back and piercing green eyes peer out on a world that has made it its business to hunt him down.

Yet if alleged serial killer, drug smuggler and violent gang member David MacDonald Carrol lives next door to you, you probably wouldn't have a clue.

Carrol was named this week by Interpol and Crime Stoppers International on a list of 60 notorious crooks that authorities across the globe are now trying to track down.

And Crime Stoppers International says fellow bikie members may well be conspiring to keep him beyond the law right here in Australia.

The 58-year-old's alleged rap sheet makes grim reading.

The Royal Canadian Mounted Police believe Carrol is guilty of 13 murders, conspiracy to murder, attempted murder, drug trafficking, participation in gang activities and conspiracy.

The crimes are all said to have taken place between 1995 and 2001 and stem partly from a drug feud with rival motorcycle gang members.

It warns members of the public that Carrol is potentially violent and not to try to apprehend him.

Crime Stoppers International said Australian bikies may well be hiding him, possibly very well disguised and under a new identity.

And it said anyone harbouring Carrol could end up facing severe criminal penalties.

The United Motorcycle Council of Australia has dismissed the idea Carrol is in Australia, saying the ongoing police crackdown on outlaw bikie gang members would make it extremely hard for Carrol to remain hidden.

But the reality is that if he is here, hardly anyone would know about it.

The fugitive would almost certainly have slipped into the country on a false passport, under heavy disguise, possibly having had plastic surgery and significantly aged from his last known photograph, taken in 1999.

Asked if Aussie bikies could be harbouring Carrol, Crime Stoppers International spokesman Peter Price said: "It's logical - people normally do reside with those they feel most comfortable with.

"They normally stick closely to people they know and trust.

"(Carrol) is associated with motorcycle gangs so it's motorcycle gangs where he's likely be most comfortable."

Mr Price declined to speculate which state Carrol could be in and admitted it was not certain he was in Australia.

Interpol notes there are dozens of other Hells Angels chapters around the world that could be protecting him.

Carrol has frequented numerous other countries including Brazil, Mexico and the US, and speaks French, Interpol says.

But he is known to have very strong links to Australia, according to police intelligence, and Mr Price said there would be people willing to hide him.

"We know these people are embedded deeply within communities," he added.

United Motorcycle Council of Australia spokesperson Margaret Lawson argues police surveillance of bikies gangs, particularly in NSW, would make it almost impossible to hide Carrol.

"I wouldn't attach too much importance to the idea that he is in NSW or even Australia," Ms Lawson said.

"We are under so much intense surveillance here in NSW, our telephone conversation right now is probably being recorded by the police somewhere, so it would not be the wisest place to be, it would be hard to hide."

This week, NSW Police applied to the Supreme Court to have the Hells Angels declared a criminal organisation.

Outlaw bikie gangs in the state have been almost constantly in the spotlight since the March 2009 brawl between rival gang members at Sydney Airport which left Anthony Zervas, 29, dead after being bashed.

A similar manhunt for Carrol launched in 2009 failed to find him, although it did locate 45 other fugitives wanted by Interpol and Crime Stoppers and resulted in eight being put behind bars.

Another alleged crook currently suspected of being in Australia is the former mining executive Jason Holland, who is accused of a large fraud against a former employer, South African resource firm Sentula Mining.

It's alleged that in 2008 he set up a bank account in Germany into which he siphoned off a large amount of Sentula's cash before vanishing.

The 42-year-old could also be in the UK or the Netherlands, Interpol says.

The bespectacled former financial director is believed to hold South African and British passports.

Interpol and Crime Stoppers International has appealed for information about both men and 58 other fugitives on the wanted list.

The organisations have launched similar appeals in countries across the globe, appealing to ordinary citizens to report possible sightings.

"The initiative is well and truly an international one. We live in a global community, and these people have family and friends, and are lurking in our communities," Mr Price said.
