Police have said they were working with local authorities to ensure the “integrity” of the independence referendum after an alleged election fraud.
A probe is underway following claims that 10 people turned up to vote only to be told that somebody had already done so in their name.
Referendum officials wearing blue gloves have been sifting through the ballot boxes to find the papers, which are being put into evidence bags.
A police spokesman said: “Police Scotland takes the safety and security of the independence referendum extremely seriously and is working with partner agencies including local authorities and the chief counting officer to ensure the integrity of the ballot.
“Any crime committed will be investigated appropriately.”
Colin Edgar, media liason officer at the Glasgow count, said: “We know which boxes that these votes went into and the numbers of those votes so police have asked us to identify those votes, to take them away and hand them to them.”
He said the issue came to light after people turned up to vote, and when they gave their name to the presiding officer they discovered it had already been scored off and a ballot paper issued to somebody who “apparently had the same name”.
Mr Edgar added: “We will find the ballot papers tonight, they will be kept safe and secure and given to Police Scotland to from their investigation.”
He said there had been 10 reported incidents, and that he was not aware of it happening outwith Glasgow.
