A MELBOURNE arson squad has arrived at the scene of a suspicious fire in Havilah Road.
An investigation is underway into the blaze that extensively damaged the Satan's Soldiers headquarters in Long Gully today.
Forensic officers in blue coveralls are also on site with one carrying two shovels to the rear of the building shortly before 2.30pm.
The 2am blaze is believed to have started at the back of the building. Today a collapsed portion of the clubhouse and smoke damage is clearly visible.
While it's not known what started the fire, police are treating it as suspicious and have cordoned off the area. Two guards have also been posted at the scene since 6am.
Residents near the clubhouse have said they've never had any dramas with the group before.
One resident told the Bendigo Advertiser he wasn't concerned.
"I've never been worried before," he said. "They've never been a problem."
The fire comes as police launched a blitz on outlaw motor cycle gangs this week amid fears a bloody feud between the Hells Angels and Bandidos could escalate into a full-scale bikie war.
In the past four days police have executed 15 search warrants, including one at a Lake Eppalock caravan park, and arrested seven people said to be bikie gang members and associates.
