Police broke up the bash at 1.20am on January 16 after receiving reports of dozens of people at a loud party at the short-term rental flat in Woodstock Street, just off Oxford Street.
Pc James Lilley said they found a party “in full swing” with empty bottles of champagne and spirits littered around the property and radioed for back-up when partygoers facing Covid fines tried to flee.
“One male threatened all of us with violence if we refused to move, and he indicated that the whole group would attack us,” the officer told Westminster magistrates.
“We stood our ground and I communicated to control that we would need assistance on the hurry-up due to the threats of violence against us.
“As people were prevented from leaving, some partygoers decided to climb over the balcony onto an adjoining roof and making their way down scaffolding that was further up.”
Fines were issued to those who remained in the property, including 24-year-old Leanne Swain from Gravesend and Melanie Walters, 28, from East Dulwich.
Both women were prosecuted after failing to pay their fixed penalty notices. Swain pleaded guilty and was fined £200, while Walters did not enter a plea and was ordered to pay £1,100 after being found guilty in her absence.
In a separate incident, Met officers came under attack when they broke up an all-night party in Brick Lane on January 15.
Details of the incident were revealed in the prosecution of Thomas Curd, 36, from Pimlico, who was found guilty of holding a gathering in breach of tier four restrictions. He was fined £1,100, after being spotted packing away music equipment.
