THE owners of a marina say someone could have been killed after vandals untied boats and let them drift into a canal.
One boat at Fairies Hill Marina in Altofts drifted to a weir and was only saved at the last moment.
Mel Smith, 63, who has a boat moored there said it could have had fatal consequences.
He said: “One boat ended up doing a balancing act on a weir, but thankfully no one was on board, as those responsible could have been facing more than just criminal damage charges.
“Who ever did it may think it was a prank, but it could have had deadly consequences.”
And windows of the boats moored at the waterways have also been smashed during the past couple of weeks.
The site on the Aire and Calder Navigation has moorings for up to 60 boats.
