Specialist officers have searched the River Leven for missing man Allan Bryant after receiving a public tip-off.

Police Scotland's Marine Unit scoured the river in Glenrothes on Thursday, but nothing was found.

The 23-year-old has not been seen since leaving the Styx nightclub in Glenrothes, Fife on November 3, 2013.

Although Mr Bryant has been missing for four and a half years, officers said their enquiries are still ongoing.

Despite extensive searches and police appeals over the last four years, no trace of him has been found.

A spokesman from Police Scotland said: "Acting on information received from the public, specialist officers conducted a search of the River Leven in Glenrothes as part of the ongoing investigation into missing man Allan Bryant.

"The search has now concluded and nothing was found.

"Anyone with information about Allan's whereabouts, or his movements after leaving Styx nightclub in the early hours of November 3, 2013, is urged to contact Police Scotland on 101 quoting Operation Toner."
