CCTV footage has today revealed a grim snapshot of life after dark in some of the secluded streets and alleys of Norwich's city centre.
The scenes captured on a security camera installed in the historic Tombland Alley will be a familiar sight to many.
And for some it demonstrates how their quality of life is being negatively impacted by living in the city.
The footage shows:
A man being dragged to the floor and repeatedly kicked
Someone smoking what appears to be crack while sitting on the wall of St George's Church, Tombland
Men and women urinating up against the church wall late at night
A man stealing a part of a sign before dumping it further up the alleyway.
The footage was recorded by Pernille Rudlin, who installed a CCTV camera on her nearby property last month.
She has since posted the videos onto Facebook in a bid to alert Norwich City Council and the police about what is happening.
Ms Rudlin, who has lived in the area for three years, said she was woken up at night almost every weekend by people in the alley.
She said she installed the camera after graffiti started appearing on the wall next to church.
'I go out every weekend and I have to get rid of broken bottles, needles, condoms and even poo from down there,' The 51-year-old said.
'It is one of the city's most historic streets, and it is embarrassing it should look like that.'
Her footage is representative of issues raised by people living elsewhere in the centre of Norwich.
Earlier this month, residents on King Street revealed how their lives were blighted by overspill from the city's night-time economy.
They said that while Norwich's night life was largely contained to Prince of Wales Road, other areas were not as well policed.
Meanwhile, police stepped up patrols in the Rosary Road area following a number of complaints about prostitution.
Ms Rudlin believed that the solution to the anti-social behaviour in Tombland Alley would be to close it off at night.
'What I would like to do is to have Tombland Alley closed off from 10pm until 7am, because it is so tempting for people to go down it,' she said.
'I can see why people think it's a great place to do something.'
She fitted the camera and floodlight to try and deter people away from using the area as a toilet.
But her footage, which is posted on the Facebook page Tombland Alley, shows it is yet to have an effect.
A city council spokesman said a number of measures had been put in place to help manage Norwich's night-time economy.
It includes new signage on residential roads reminding people to respect people living nearby at night.
CCTV cameras have also been installed on Cathedral Street and Bank Plain/Queen Street.
The council said there was also improved policing of the night-time economy areas, including Prince of Wales Road.
Meanwhile, in 2014 it introduced new access restrictions on Cathedral Street, St Faiths Lane and Recorder Road between 11pm and 6am daily to reduce noise to residents.
But the spokesman said its powers were limited regarding Tombland Alley, as it was an adopted highway rather than a residential street.
'The city council has been working with the police and other organisations to help tackle any negative effects of the night-time economy on residents, businesses and visitors within the city centre,' the spokesman said.
Lesley Grahame, Green Party councillor for Thorpe Hamlet Ward, which covers Tombland, said she had received some complaints from people in the area.
'If you live in the city, you expect a bit of noise, but you don't expect that sort of anti-social behaviour and you should have to put up with it.'
Norfolk Police said it was 'aware' of reports of anti-social behaviour in Tombland Alley.
A police spokesman said: 'Officers are investigating these offences and are trying to identify suspects involved using camera footage obtained by a member of the public.
'Anyone with information about illegal drugs activity, or is concerned about suspicious behaviour, should contact Norfolk Constabulary on 101.'
