A "wild, out of control woman" refused to release her grip on two women's hair - despite police officers punching the back of her wrists and pressing their thumbs into her neck, magistrates heard.
Qualified nurse Donna-Marie Campbell, 34, eventually let go after several minutes, leaving both women very upset, and one with a black eye, the court was told.
Campbell, of Brougham Street, Skipton, claimed she suffered anxiety, had just had extensive dental treatment and had acted in self defence and fright after being taunted by a "bully squad" as she lay on the ground in the rain outside the town's Wetherspoons Pub at around 1am on February 8.
But Skipton magistrates found her guilty of two assaults by beating after hearing from three police constables and a sergeant who described her as being drunk, very angry, wild and out of control.
They told her she had acted out of character because of drink and gave her a 12-month conditional discharge. But they ordered her to pay £150 compensation to each of the two women, costs of £100 and a victims surcharge of £15.
