A primary school has installed a 10ft fence to ensure students don't see "threatening gestures" and "extensive problems with crime."
Twickenham Primary School in Kingstanding, Birmingham, decided this was necessary after children were allegedly subjected to anti-social behaviour and intimidation.
A council planning report claimed the school had reported 39 incidents to West Midlands Police since January 2016.
Nine of the reports were in relation to unauthorised access of the school grounds.
The school has said since the fence was put up "as a last resort" last year due to the "severity and regularity of crime," it has now reduced significantly.
The report by Birmingham City Council's planning committee said: "The school wishes to erect the fence in order to provide greater security, prevent trespass on the site and prevent individuals from intimidating pupils from the gardens on the other side.
"It is evident that Twickenham Primary School has suffered relatively extensive problems with crime and anti-social behaviour in recent years.
"The school also wishes to limit visual interaction between the residential properties and the site, as a result of incidents where individuals have tried to intimidate pupils with inappropriate and threatening gestures."
The report also claimed the police force was in favour of the fence so that significant levels of crime which have taken place within the school grounds could be combatted.
It added: "The police's subsequent investigations of the incidents have suggested that offenders are moving from one rear garden to another in order to access the school, exploiting any 'weak spots' they come across in the boundary."
However, some local residents have complained that the new fence has an "industrial and gloomy appearance and it has given their gardens a "prison-like feel."
Locals have also argued that the small gap between the school fence and an adjacent fence will gradually fill with rubbish and therefore attract rats and vermin.
