Two Adelaide blazes may have bikie links

Outlaw bikie gangs may have played a role in two suspicious fires in Adelaide's south.

The first blaze at a tattoo parlour in Morphett Vale started after a Molotov cocktail was lobbed at the shop at about 1am on Thursday.

Less than two hours later, a fire started in a garage at a unit block in Seaford, destroying three cars and other personal items.

No one was hurt in either incident.

Police believe the two fires are linked, and are investigating whether they may be connected to outlaw motorcycle gang activity.
