THE Electoral Office has apologised for an "administrative error" that led to a man being prevented from voting.
It is understood the man found his name was already marked through on the register when he tried to vote at St Joseph's Primary School in Ederney, Co Fermanagh last week.
Graham Shields, the chief electoral officer, said there was no evidence of any fraud.
He said it appeared the problem last Thursday resulted from an "administrative error by one of the poll staff".
"Whilst incidents such as this are extremely rare, I would nevertheless like to offer my sincere apologies on behalf of the Electoral Office to the gentleman concerned for any embarrassment or annoyance that has been caused," he said.
"Unfortunately once a name is marked through on the register another vote cannot be issued in that name."
The assembly election saw Richie McPhillips gain back a seat for the SDLP in Fermanagh and South Tyrone after Sinn Féín faced vote-management issues due to fielding four candidates.
Sinn Féin's Michelle Gildernew and Sean Lynch were elected but party colleagues Phil Flanagan and John Feely lost out.
DUP leader Arlene Foster, her party colleague Maurice Morrow and the UUP's Rosemary Barton were also elected in the border constituency.
