POLICE are appealing for witnesses following two separate "fail to stop" collisions in Gwynedd which left a driver and cyclist hurt.

The cyclist sustained serious injuries following the first collision near Trefor.

At approximately 4.05pm, on Tuesday, May 22, police responded to a report of a collision on the A499.

A cyclist had been struck by a dark blue Mercedes which failed to stop.

The cyclist was taken to Ysbyty Gwynedd in Bangor with serious but not life threatening injuries.

A short while later, the same vehicle was involved in a second fail to stop collision on the A499, on the outskirts of Pwllheli, where it struck a Vauxhall Zafira. The Zafira driver sustained a minor injury.

The driver of the Mercedes was traced in the Pwllheli area and was arrested on suspicion of motoring offences.

Police enquiries are ongoing and officers are appealing to anybody who may have witnessed either collision, or who may have seen the dark blue C200 Mercedes being driven along the A499 from the Caernarfon area towards Pwllheli and who may have dash cam footage, to contact officers at the Roads Policing Unit on 101, quoting reference number W067079.
