South East Queensland riders have been out searching for a 66-year-old Sandgate rider who has been missing since Monday when he set out for a “joy ride” to Esk.

Siemon Mulder left Sandgate at 9am this morning to ride his blue Triumph Sprint ST registration 769DW (pictured) to Esk and planned to return home by noon. He has not been heard from since.

Police have confirmed this morning that he is still missing and have called for public help to locate him.

Riders have responded with dozens scouring the region’s popular motorcycle routes over the past couple of days.

Police helicopters have also searched the area by car and helicopter.

“Police and family hold concerns for his safety as this behaviour is out of character,” Police say.

Siemon is about 180cm tall with a slim build, grey short hair and grey facial hair.

He was last seen wearing a black leather jacket, blue jeans and black helmet with a dark tinted visor.

Police say he was a cautious rider, but they are considering he may have had an accident.

They have checked his mobile phone which was last used in Sandgate and say he always uses cash when out on the road.

Searching for clues

If Siemon has run off the road, riders should be searching for skid marks on the road or verge, broken glass and plastic on the road, bent-back bushes and the glint of shining objects in roadside bushes.

Riders searching for Siemon should also take care if they are riding slowly not to hold up traffic, use their hazard lights and take care of their own safety.

It’s a good lesson for all solo riders to tell others where you are going, take your mobile phone, download locator apps or, if in remote areas, pack an EPIRB, beacon or GPS tracker.
