text: More than 70,000 people across the world have signed a petition demanding McDonald's remove spikes that deter the homeless from sleeping outside one of its restaurants. The fast food giant has caused fury after installing metal studs outside its branch in Leeds city centre, which critics say are there to stop people  sleeping rough. McDonald's has defended the use of the spikes, claiming they were installed two years ago in an attempt to stop anti-social behaviour, not target the homeless. Uproar: A petition has been started to get the spikes removed from outside this Leeds McDonald's and 70,000 have backed the campaign . But critics say they have been put in because they are uncomfortable to sleep on and installed on areas which used to be benches. Isobella DeMartino set up the petition to have them removed and has received support from across the globe. Row: Critics say the spikes were installed to target the homeless but McDonald's say it is only about anti-social behaviour . 'Anti-homeless spikes show complete disregard and lack of respect for homeless people who struggle every day,' she said. 'Spikes have been installed, presumably to prevent people sleeping there. 'The fact that the spikes exist shows how little people care about homeless people.' She added: 'Every time I'm in Leeds I see many ignore homeless people, not even bothering to smile at them let alone try to help them or give charity. I cannot imagine how painful and lonely it must be to be homeless. 'They deserve our attention and care, this issue cannot be ignored.' A spokeswoman for McDonald's said: 'The studs in question are not an 'anti- homeless' measure, as has been suggested. 'They have been in place for around two years and were introduced Following discussions with the police, in response to issues we were experiencing with antisocial behaviour. 'We welcome all customers through our doors and it is inaccurate to suggest a measure taken in response to tackling antisocial behaviour, is an attempt to deter homeless people.'
