Cardiff university has installed metal cages by warm air vents on campus saying it is due to health and safety measure.
The students beg to differ saying the vents are there to stop homeless people sleeping by them.
This comes not long after a Tesco branch in London provoked outrage with “anti-homeless spikes” outside a shop, following a similar move outside a flat development.
The supermarket denied the one inch metal studs were to stop homeless sleepers, saying they were aimed to stop groups drinking outside and intimidating customers.
The Independent Reports: “Students say they are “disgusted” by the move but the university claims the grilles, outside a chemistry building, are necessary for health and safety.
Student Lewis Hopkins, who blogged about the cages after spotting them on his daily cycle to university, said he was “sickened”.
“The homeless people are never there in the day, it’s only overnight,” he told The Independent.
“They never caused any trouble, never littered nor gathered in groups,” he added.
A Cardiff University spokesperson stressed that the grilles were installed outside the Sir Martin Evans building “in the interests of health and safety”, not to deter homeless people.
“The area covered by the safety grilles are not hot air vents but boiler flue vents that can potentially produce products of combustion – diluted amounts of carbon monoxide being one of these – as part of the diluted boiler flue gases,” he added.
“These vents are considered safe in normal use due to the type of flue dilution system being used but there could potentially be an increased risk if people are sleeping right next to the grilles for very long periods.”
He said the university had been working with security staff on the issue and said the cages would reduce risks to anyone sleeping nearby.”
