A new business that will deliver alcohol to homes in Exeter has been criticised by police.
Party Cellar has been granted a licence by Exeter City Council. It will deliver drink to homes in the area from 8pm until 4am.
Police said they were concerned it could make alcohol-fuelled violence worse and promote binge drinking.
The company said it was to run a professional service and its work could cut risks of people drink-driving.
Orders will be phoned into a central warehouse and sent out using a fleet of vans.
The company said being able to deliver orders meant people who had already been drinking were less likely to drive to buy more alcohol if they ran out.
Andy Pillinger-Brown, from the company, said: "We're not looking to create any problems for the police or where we're delivering to.
"It's a professional service we're going to offer, and it's no different from somebody ordering a taxi and being driven to their local 24-hour store."
But police said their main concern was alcohol-related disorder if people who were already drunk went home and ordered more.
Acting Inspector Tom Cunningham, of Devon & Cornwall Police, said: "Clearly there is the potential for alcohol-related anti-social behaviour, and we're concerned about possible effects on local communities."
Exeter City Council said that its licensing sub-committee found no evidence for a reason to refuse to grant the licence or restrict it.
The company is expected to begin trading within a few weeks.
