Historic Herdman's Mill 'significantly damaged' in arson attack
The historic Herdman's Mill in Co Tyrone has been targeted by arsonists once again.
A fire broke out at the Sion Mills derelict site on Sunday night just after 9pm. Fire fighters from Strabane, Londonderry, Castlederg and Newtownstewart were sent to the scene to tackle the blaze which lasted until around midnight.
The fire service said the building was "significantly damaged" and they were treating it as arson.
There have been a series of attacks on the site over the years - including two in the space of as many days last June.
In 2014, Herdman's Mill was bought by Strabane woman Margaret Loughrey for £1m after she won almost £27m in the Euromillions lottery draw.
In October 2015, the historic mill complex was seriously damaged in another blaze. And back in August 2011 the mill suffered major damage in another fire.
The linen mill dates back to 1835 and once employed over 1,000 people.
