Road closures are still in place this morning as firefighters work to make a derelict building destroyed by a large fire safe.

Acer House, in East Street, Epsom, burst into flames in the early hours of Wednesday, February 19.

A public exclusion zone, road closures and diversions were put in place yesterday as the building was deemed to be unsafe.

A 54-year-old man arrested yesterday has been released on bail until March 7, police said this morning.

DC Jemma Daly said: “This was a large blaze and has caused enormous damage to the property and major inconvenience to motorists in the area.

"I am appealing for anyone who may have witnessed anything or anyone acting suspiciously in or around the location to contact officers with any details."

FROM YESTERDAY: Epsom fire - "I have never seen fire ravage anything so quickly"

This morning Surrey Police said East Street was open one-way heading from Ewell Road towards Epsom town centre, but was still closed heading from the town centre towards Reigate Road and the A24.

Police Inspector Jackie Elkins said the road would probably remain closed throughout the day while the fire service carried out further work on the building and it was made safe.

This morning Epsom and Ewell police tweeted a photo of Acer House, showing its roof had been removed. It said: “...demolition work completed.”

On its Facebook page in the last hour, it said: “Work is currently taking place on Acer House, East Street.

"If possible please avoid the area as it’s very busy.”

Acer House was empty at the time of the fire and no one was injured.

It is understood that it was due for demolition and had remained vacant since it shut in 2011 as a centre providing support to people with mental health problems, drug and alcohol problems and learning disabilities.

It was run by Surrey and Borders Partnership NHS Foundation Trust.

Yesterday Evi Loizou, whose mother lives in Middle Lane, behind Acer House, said her mother had seen people “coming in and out of the building” since it had been empty and a week ago she saw a young man entering it from the back.

On the blaze, Ms Loizou, who was staying with her mother at the time, said: “We thought the embers might blow onto our house but the wind was blowing away from it.

"We did wonder whether people were living in there and started a fire to keep warm."
