Three Glasgow men have appeared in private at Perth in connection with the attempted murder of two Fife men at T in the Park on Sunday.
Robert Lindsay (23), Iris Avenue, John Dorfman (22), Ballantay Terrace, and Joseph Lindsay (25), Hoddam Road, all Castlemilk, Glasgow, appeared before Sheriff Pamela Bowman on Tuesday.
The charges alleged that all three attempted to murder Nicholas Gallacher and Robert Hynds by striking them on the body with a knife.
Dorfman also faces a charge that he assaulted Mark Bell by punching him on the face.
They made no plea or declaration and the case was continued for further examination.
The Crown made no opposition to bail and all three were released on condition they take part in an identity parade.
