Buckingham Palace maid arrested for assault after boozy brawl at staff Christmas party: ‘On another level’

It was a royal rumble.

A Buckingham Palace maid was arrested for assault following a boozy brawl at an off-site staff Christmas party.

Roughly 50 Palace staffers gathered at All Bar One in London on Tuesday for seasonal festivities that were abruptly derailed by the 24-year-old maid, according to a report from The Sun.

The maid of dishonor allegedly threw a punch at a bar manager and made a scene of hurling and breaking glasses inside and outside of the bar, according to the report.

She allegedly tried to duke it out with security guards before the bobbies were called to hall her away.

“I’ve never seen one person that crazy during a night out. She was on another level,” a witness told The Sun.

The young maid spent the night in jail and was released the following day with a fine, The Sun reported.

It was a “tough night” for the flock of palace employees, another source told the outlet.

Buckingham Palace said it is investigating the incident.

“We are aware of an incident ­outside the workplace involving a ­number of Household staff who had previously attended an early evening reception at the Palace,” a Buckingham Palace spokesperson told The Sun in a statement.

“While this was an informal social gathering, not an official Palace Christmas party, the facts will be fully investigated, with a robust ­disciplinary process followed in relation to individual staff and appropriate action taken.”
