South Yorkshire Police website hacked by 'Albanians'
South Yorkshire Police's website has been hacked by a group purporting to be from Albania.
Following Sunday's hack, the front page of the site showed an Albanian banner and a carousel of images including football fans at Euro 2016.
It later changed to a message claiming "no data was leaked" and signed "Albanian Hackers".
A security expert warned the attack is "potentially very serious".
By 15:00 BST the site appeared to have returned to normal.
The first image posted by the group proclaimed: "It's Good To Be Albanian."
Later, the red and black image was replaced by text on a white background.
The message read: "no worry no data was leaked or deleted, simple a deface page was uploaded."
Last year, the Daily Mail reported a hack on Falmouth Town Council by the same group.
