Birmingham's cult “greasy spoon” cafe Mr Egg has been temporarily shut down on health grounds.
Environmental health inspectors slapped the famous takeaway with an emergency probation notice amid concerns of food contamination, cockroaches and mouse activity.
The move comes just days after 13 people were injured after being sprayed with a substance, thought to be undiluted vinegar, in a late-night disturbance at the Hurst Street cafe on Sunday.
Police dealing with the incident raised concerns with the environmental health officers who issued the notice.
A notice on the door of the premises, which stands in the shadow of Birmingham’s Hippodrome theatre, said it was closed under the Food Hygiene Regulations because of an “imminent risk to health”.
The notice, issued on Tuesday, listed the risks as mouse activity, cockroaches, lack of effective cleaning and food at risk of contamination.
It said the takeaway, a popular late night destination for city centre pub and club-goers for about 15 years, could not be opened again until permission had been granted.
Closed signs could be seen on the doors and cardboard was placed in the windows.
A spokesman for Birmingham City Council said: “Police investigating an assault reported concerns to officers. The premises was closed on the grounds of imminent risk of injury to health.
“A schedule of work has been issued and it will remain shut until that is completed.”
Meanwhile, police said they were continuing to investigate an incident at the eatery which left a number of people complaining of burns to the face after being sprayed with a substance.
One man, aged 20, today remained in hospital receiving treatment for the burns.
A 38-year-old man, understood to be a member of staff, was arrested in connection with the incident and later released on bail pending further inquiries.
Mr Egg has twice been named among the Greatest Greasy Spoons in Britain, first in a national survey in 2003 and then the following year in a poll by Morgan Stanley credit card where it was voted a favourite for a fry-up.
West Midlands Police have appealed for witnesses to the assault in the early hours of Sunday to call 0845 113 5000.
