Search-and-rescue crews combed the forest on the lower slopes of a North Shore mountain Saturday, looking for a Vancouver man missing for eight days.

Daniel Hughes, 29, has not been seen since June 5, when it's believed he went for a bike ride and didn't return home.

Police got their first clue as to his whereabouts Friday after his bicycle and helmet were found locked to a tree on Mount Seymour in North Vancouver.

"A dog walker…found his bike locked against a tree and off the beaten path. It's a bit peculiar, but it tells us maybe that he didn't want to be spotted going into these trails," said Sgt. Kirk Star of the Vancouver Police Department.

He said Hughes disappeared just three weeks after getting married, and was facing increasing pressure at work.

"Locking his bike is a good sign, assuming he wants to come back to it. Maybe he just needs some time away."

Star said witnesses first saw the bike last Saturday, one day after Hughes was reported missing.

The rescue team includes 25 search and rescue members on the ground with several dogs, a police helicopter, and kayakers searching the shores of the Seymour River.

Hughes is a Caucasian male, six feet two inches tall, 180 pounds with short brown hair.

Vancouver police are asking anyone with information to call 604-717-3321.
