A group of bus drivers from Corby in Northamptonshire have reportedly scooped Friday's £38m EuroMillions jackpot.
Twitter users said rumours about the win were rife in the town.
Jerry Wright, a local DJ, posted: "12 Corby based bus drivers scoop the Euromillions last night, the whole town is talking about it, try getting a bus in corby today! lol."
Camelot, however, has only confirmed that a UK ticket-holder claimed the prize on Saturday morning.
James Fox, a driver at the nearby Kettering bus depot, posted: "We worked out who they were though because seven of them... never turned up for work, and to be fair I don't blame them."
One driver walked off his bus mid-shift after learning he was set for a £3.1m windfall, the Sun reported on its website.
Just one ticket matched all seven of Friday's numbers - 3, 4, 12, 23 and 50, plus the lucky star numbers of 4 and 7 - so if the syndicate's claim is validated they will take the entire jackpot.
It is the fifth time this year that the EuroMillions top prize has been claimed in Britain.
Earlier this month, a UK ticket-holder scooped £22.1m in the draw, but opted to remain anonymous.
That win came just a week after another UK ticket matched the winning numbers to pick up £46.4m.
Nottingham couple Cassey Carrington and Matt Topham , both 22, scooped £45.1m at the beginning of February.
And on January 20, husband and wife Gareth and Catherine Bull , from Mansfield, banked £40.6m.
But they all come a distance behind the biggest-ever EuroMillions prize which came in July when Colin and Chris Weir , from Largs in Ayrshire, won an astonishing £161m.
