The winner of the gigantic €86.7m EuroMillions jackpot has made contact with the Lotto offices.

Although the winning ticket is believed to have been sold in the capital, it is yet unknown if the winner is a local or if it is part of a syndicate win like last week's Donegal Irish Lotto winners.

Meanwhile, the rumour mill has been working overtime.

Donabate in north Co Dublin emerged as being the strongest probability where the ticket may have been sold, with locals feverishly speculating about the winner's identity.

However, businesses in the town insisted they had heard no confirmation about Friday's massive win.

A staff member at SuperValu in Donabate revealed he had heard the rumours that the ticket had been sold locally, but said: "It wasn't us."

"There's big excitement in the area. We've heard it could be one of the garages," he said.

At the Maxol garage in Donabate, staff said they were not sure if they had sold the ticket, but said nobody had been in to say anything about it.

"All the staff would have been told that somebody had bought a winning ticket, so I'm not too sure," said a member.

At the Centra shop in the Great Gas Junction Four, a staff member said he too had heard the rumour, but said nothing had been announced.

"There are probably another 10 shops in the Donabate area that sell the Lotto, so it could be any of them," he said.

A staff member at the Topaz garage in Donabate told a similar story. "I heard exactly the same thing - one of the customers was in asking if we had sold it.

"But nobody's come in with a winning ticket so far," he said.

The head of marketing at the National Lottery, Eddie Banville, said they were thrilled about the win.

They are aware of where the ticket was purchased, but will not be revealing the information until the lucky punter has had time to process their win.

The winning numbers drawn were 6, 8, 34, 38, and 48, the Lucky Stars were 3 and 9.

This is the fourth jackpot win of the EuroMillions in Ireland since June 2013. The last big Irish EuroMillions win was in June 2013, when a mystery person scooped €94m.

In September 2013 another winner won €12.8m, with the most recent jackpot win, worth €15m, claimed last March.

The National Lottery advises that if you are the winner that you should keep the ticket safe and make sure that you sign the back.
