It could become more difficult for pubs and clubs in York to extend their opening hours in future.
The police have asked the York Council to crack down on premises within the cumulative impact zone (essentially the City centre) which seek longer opening hours.
The move comes against a background of increasing violence and disorder on some City centre streets.
The restrictions would affect any premises wanting to extend their hours to open beyond 11:00pm and also any licences seeking an overall increase in opening hours each day.
A report will be considered by the Council on 25th April. If approved the proposal will be subject to public consultation.
