Firefighters are still tackling a fire at a Sherwood factory, more than seven hours after they arrived at the scene.
The Sherwood Works, in Nottingham Road, which is believed to be a clothing factory, was evacuated overnight.
The major blaze broke out at the SQP International factory behind Sainsbury's, off Valley Road at around 1.20am on Thursday July 31.
The owner, Lamber Johal, is away in India at the moment, but is making arrangements to get back.
His daughter Palo Basi was at the scene this morning and said he is "devastated".
Dozens of staff from Jones and Co button manufacturers next door were waiting by the cordon at the junction of Lortas Road and Nottingham Road while firefighters continued to put the flames out.
Sharon Brown, 40, of Hyson Green, works at the factory next door.
She said: "We are just waiting for instructions from our director.
"It looks like it has been a very bad fire. I heard about it on the news but it is still a shock to come and see this."
Her colleague Darren Saxton, 34, of Basford, thought he was arriving for a normal day at work.
He said: "I didn't expect to see this. It was a real shock when I arrived.
"The factory looks a bit of a mess. It looks like it has been a really bad fire."
Fellow colleague Sandra Brandom, 51, of Bulwell, said: "I saw it on the news when I got up and it looked really bad.
"I came down here as I wasn't sure what the situation was with my factory."
Mark Dickins, 51, who lives in Nottingham Road, returned home from a night shift at work at 3am.
He said: "Part of Nottingham Road was closed off. They only let me through as I live here.
"I could see the flames. It was lighting up the sky.
"When I got up they were still putting the fire out. Sadly the building looks destroyed."
An insurance assessor at the scene said: "That building will have to come down."
The firm has been based in the building since the 1970s.
Firefighters came from as far away as Retford to tackle the flames.
Incident commander Mark Mortimore, of Retford Fire Station, said: "When we got here the building was well alight.
"The fire has caused extensive damage to the building. We are unsure of the cause at this stage. Structural engineers from the city council are assessing whether it is safe for us to go in."
Yvonne Wyer, 75, who lives in Nottingham Road, was woken by the sirens.
She said: "I heard them and saw blue flashing lights.
"I looked out and could see the flames reaching a long way into the air."
