A City Council spokesman said: "We treat these incidents very seriously and were alarmed to hear of this attack. Our sympathies are with the victim and we will be reviewing our policies in light of this latest incident.
'We have been carrying out regular patrols of the park but we cannot have a permanent presence there. So far we have not witnessed any recent problems in Belmont Park but would ask members of the public to contact the police if they have any information about this incident or any others in the park or other parts of the city."
