A biker "left the scene" of a serious three-vehicle crash which has shut a road.
Police are appealing for witnesses after the crash on the B5119 between Rhyl and Dyserth at around 6pm on Monday.
The force said that the crash, which they have described as "serious", involved a Black BMW X1 and two motorcycles.
One of the motorcyclists left the scene of the collision, the force said.
A spokesman said: "They were travelling from Rhyl towards Dyserth .
"We are particularly keen on speaking to anybody who may have been travelling in or around the vicinity and who may have dash cam footage to contact us on 101 quoting X065624."
