Police were called to the restaurant at 12.20 am on the night of the attack. They reported that Rhys Copas suffered an 8 cm wound that exposed his voice box and damaged nerves. The suspect, identified as Lucci Guthrie, 28, has been charged with attempted murder and is due to appear at the Old Bailey, as reported by MyLondon.
Licensing hearing and imposed conditions
The venue voluntarily closed after the attack and its licence was temporarily suspended pending a full hearing on 7 September 2026. At the hearing, Westminster City Council representatives highlighted failures such as operating like a nightclub, not scanning the suspect’s ID and allowing door staff to work without distinctive uniforms. The council concluded that the premises could stay open if it complied with specific restrictions.

The conditions attached to the licence require the venue to end alcohol sales earlier on Sundays, prohibit the conversion of the space into a dance floor and ensure that security personnel wear clearly identifiable clothing. These measures aim to address the safety concerns raised by both licensing officers and police.
Management changes
Following the incident, the venue’s former General Manager was replaced. Legal counsel for the licence holder, Gary Grant, said the priority has been the victim’s welfare and restoring confidence for future customers.
What happens next
The Mistress of Mayfair must demonstrate compliance with the new conditions during regular inspections. Failure to meet the requirements could lead to further enforcement action, including possible revocation of the licence. Patrons are advised to note the earlier Sunday closing time and the absence of a dance floor while the venue implements the security uniform policy.
