Pesky pigeons have prompted council bosses to seek measures to prevent the birds' fouling from creating a 'slip hazard' for staff at City Hall.

Norwich City Council has submitted a scheme to its own planning department to install a post and wire system at the back of the Grade II* listed building.

Documents lodged in support of the application state that the 'roosting of pigeons has resulted in an accumulation of fouling'.

The council states: 'This persistent pigeon fouling not only looks unsightly but also poses the risk of disease through inhalation or direct contact.

'Due to its position adjacent to an emergency exit, it currently presents a slip hazard and therefore these works will have a positive effect on access to City Hall employees.'

The council says, due to City Hall's Grade II* listed status, a 'low visual impact system' is proposed to tackle the problem.

This is not the first time bosses at City Hall have tried to deal with the pigeon problem.

In 2012, the council tried to protect the 1930s building using a gel to trick pigeons into believing the landmark was on fire.
