Licensees in Derbyshire are being urged to check the conditions of their licence carefully after two pubs were issued with closure notices.
Police carried out a series of spot checks on 23 pubs across the district, which led to eight warning notices, two closure notices and two notices for having insufficient door staff.
The checks were part of Operation Relentless and also involved environmental health officers.
Warning notices were issued for minor offences such as not displaying the required notices to ensure customers left the premises quietly.
Closure notices were issued for not having CCTV in working order and licensees were given 14 days to fix the problem or face closure.
"It's disappointing that some supervisors and licence holders are not aware of what their licence means and the regulations they have to meet," said licensing officer PC Sandra Barlow.
"We would urge anyone unsure of what they need to do as part of their licence to contact their local licensing authority."
