Search continues for missing Tas man

Police continue to seek public information about missing Launceston man Michael Hamlyn almost three weeks after he was last seen.

The 20-year-old, who is also known as Miguel Williams, did not show up for work on July 10 and investigators have since circulated images of him and the black Suzuki motorcycle he was riding.

There have been sightings of Mr Hamlyn south of Launceston at Perth and in the Fingal Valley on the day he vanished and police have previously said he could have travelled to Victoria, and while there are concerns for his welfare there are not thought to be any suspicious circumstances.
