A man was allegedly "slashed in the throat' in a nightclub with police investigating the 'serious incident'.
North Wales Police (NWP) were called to Club One47 on Upper Mostyn Street, Llandudno at around 3am this morning.
It is understood a man was taken to hospital to be treated for his injuries, which are not believed to be life-threatening.
Locals told North Wales Live that a man was "slashed" in throat and head at the venue - although this has not been confirmed by emergency services.
A police investigation at the club is currently ongoing and officers remain at the scene.
It is not yet known whether any arrests have been made.

A spokesperson from North Wales Police earlier said: "We can confirm that an incident took place at the location early hours and officers are still at the scene."

The nightclub took to social media to issue a statement on the incident.
