"The road was fully open when the fire started. We were alerted to it by passers-by who noticed smoke coming from the roof.

"We quickly closed it off to keep the public away from the scene.

"Police will stay sitting with it for the meantime while we make the area safe and the investigation is completed.

"Luckily nobody was hurt."

An eyewitness said that Regent Road had been evacuated while emergency services dealt with the flames.

"There were a fair few firemen round the back on Roman Place in breathing apparatus," she said. "It seemed like quite a big deal.

"You could hear even more sirens on the way when I was there at around 3pm."
