Police have confirmed they are investigating a bizarre independence referendum conspiracy theory in which an internet blogger claims to have come into possession of a bag of discarded Yes votes. 

The man, who calls himself John Son of David, claims in a video posted on YouTube that he received an anonymous phone call telling him to collect a carrier bag that was left close to a bin in Duke Street in Glasgow.

He then shows several ballot papers with a cross in the Yes box, which he says he believes is evidence of electoral fraud.

The clip has been viewed more than 60,000 times since it was posted over the weekend.

The Herald has been told by a source close to the blogger that the apparent ballot papers have been handed in to Police Scotland, although the force refused to confirm whether or not that was the case.

A Police Scotland spokesman said: "We have been made aware of this matter and are looking into it."

Conspiracy theories regarding the referendum result have become widespread since the September 18 poll , with almost 100,000 people signing a petition calling for a revote due to evidence of fraud.

Around 1,500 people attended weekend rallies calling for a rerun.

Chief counting officer Mary Pitcaithly has said all the counts "were properly conducted and scrutinised".
