A Brandon woman celebrating her fiancée's last day of work said, what was supposed to be a fun night out, ended early after a horrifying attack.

Nicole Fayant, 22, has a broken jaw and bruising on her face after she said a group of men attacked her on the dance floor at Houston's Country Roadhouse in Brandon.

"My jaw's split in half," said Fayant who is waiting for a call from Health Sciences Centre to go for surgery in Winnipeg this week.

She can't eat solid food and has been living off a diet consisting of protein shakes and crushed pills for the pain.

Fayant said she was at Houston's Saturday with her fiancée Desiree Fisher, 24, and another friend when they were approached by a group of men on the dance floor.

Fisher said the men were trying "to grab" her and her other friend and that's when Fayant asked the men to leave her friend and fiancée alone.

Within minutes, Fisher said the men began pushing Fayant, knocked her to the ground and continued to attack her until she was unconscious.

Fayant said she woke up in the back of an ambulance not knowing what happened and was taken to Brandon Regional Health Centre for treatment.

The Brandon Police Service said officers were called to Houston's at around 1 a.m. Sunday morning for a report of an assault.

Police said the suspects fled the scene and have not been identified.

Brandon Police are still investigating.

Fisher said no one at the bar intervened and that the men ran off without being questioned by security staff.

Royal Oak Inn and Suites General Manager Aaron Tycoles said he's aware of the assault.

Tycoles said he and the bar manager are reviewing security footage and information collected from bar patrons when they scan their identification at the door.

Tycoles said he hopes they're able to help police identify the perpetrators.

He said Saturday was a violent night at the bar with three security staff also assaulted in separate incidents.

He said one of the doormen witnessed part of the assault on Fayant but that by the time he saw, it was too late and the men had already left the bar.

Fayant and Fisher hope police are able to identify the men and that they are held accountable for their actions.
