A group of hackers believed to be supporters of the Islamic State of Iraq and Syria (ISIS) militant group took control over a UK rugby team website on Monday.

The hackers led with a banner declaring “I love ISIS,” under which they posted a message claiming the “State of Islam” is expanding, the Keighly News reported.

The Keighley Cougar’s twitter account alerted fans and followers of the hack, apologizing and assuring that developers were working to reclaim control.

The website has been restored to its original content.

“It’s sinister what’s happened and whatever organization, wherever it is in the world should be using its own media, not hijacking other people’s” Gary Fawcett, Keighley Cougars chairman told the Keighly News.

He said his primary concern was the club’s younger fans who may have been exposed to some of the photos that were posted on the site, which he said were graphic.

“It is a concern that children might see some of those nightmare images,” he said.

Several residents and fans contacted authorities about the occurrence, a spokesman for West Yorkshire police said

“We are aware of this incident and have now passed it to our counter-terrorism unit.”

“We will work with the club in relation to this and are making enquiries,” he added.

The instigators call themselves Team System Dz, who were also involved in another high-profile incident in July when they hacked more than 200 websites where they posted anti-Israeli messages, the Daily Mail reported.
