Crash investigators have seized a truck believed to have been involved in a fatal crash at Waterfall.
Paul Snepvangers, of Kirrawee, died on Wednesday after crashing his motorbike there.
Evidence at the scene suggested a truck was involved in the crash.
Mr Snepvangers' family appealed this week for anyone with information about the crash to come forward.
Investigators released CCTV footage of the truck yesterday, then seized a Hino flat-bed truck during a raid at Helensburgh this afternoon.
