Police have objected to a bar's application to hold all-night discos because they said the applicant has a string of criminal convictions.
Andrew North, of Synergy bar, in Church Gate, Leicester, has asked Leicester City Council for permission to extend the bar's opening hours until 10am on six days this month and next.
But police have asked the authority to turn down the temporary event notices applications because they said Mr North has 24 previous convictions – for crimes such as violence, driving offences, damage to property and theft.
In a letter submitted to the council ahead of a licensing hearing on Friday, Pc Tejas Mavani, of the city police licensing unit, said: "This clearly shows the applicant has a history of violent offences, as well as failing to abide by the law of the land and, therefore, it is highly questionable whether he is a fit and proper person to uphold the licensing objectives.
"The applicant has also been part of managing other premises in the city where we have had issues relating to licensing and noise."
Pc Mavani listed three encounters Mr North had with the police – a conviction for battery in June 2011, a caution for a public order offence in June last year and a conviction for common assault in September.
Bar co-owner Bimal Parmar already has a licence to open until 1am, Monday to Thursday, and until 2am on Fridays and Saturdays.
Mr North has applied for a temporary event notice for 2am to 10am on February 23, 24 and 25 and March 2, 3 and 4.
In his objection, Pc Mavani said officers thought this would encourage people to drink more.
He said: "This is likely to lead to a higher risk of crime and disorder and also persons exiting the premises at a time when families are in the area for shopping.
"It is our opinion granting this temporary event notice will put the public at risk."
Mr North did not respond to a request for comment.
Mr Parmar said he did not know about any previous convictions Mr North had – or the fact this would affect an application – and had he known he would not have allowed him to apply for the licences.
He said Mr North was not organising the events and worked as a cleaner and labourer in the pub.
Mr Parmar said: "It's just that he was going to the council so he put the name on the application. We are organising it, not him.
"They should not stop us doing it because he is only working here."
He said if the licence was granted, the bar planned to stay open until 6am.
Officers have told councillors they could choose to reject the event applications, impose conditions on the event, or disregard the police objection and allow the event to go ahead as outlined in Mr North's application.
