Residents evacuated from 200 properties in Derby remain out of their homes after a major incident was declared and two men were arrested on suspicion of explosives offences.

Derbyshire Police said searches at properties in the Vulcan Street area of Derby were continuing on Friday and affected residents had been offered accommodation in hotels.

People were told to leave their homes on Thursday after Derbyshire Police carried out a warrant following intelligence about materials at a house in Vulcan Street.

Two men – one in his 40s, another in his 50s – were arrested on suspicion of explosives offences, and are currently in custody.

The force said it was not being treated as a terrorism incident and that there was “no wider risk to the community”.

A cordon remained in place and people would not be allowed to access properties until further notice, the force added.

Officers said residents with any concerns regarding medication, could visit Shaftesbury Crescent, north car park, where there were medical professionals available to assist and advise.

The Pakistani Community Centre remains open as a contact point for anyone in the area, the force said.

It added Derby City Council had public protection officers and colleagues from their neighbourhood teams working in the area to provide reassurance.

When asked by the BBC whether people who live in the evacuated zone would be able to return to their homes on Friday night, Supt Becky Webster said: “I don’t want to say that will be a definite.”

Supt Webster added police were working with other authorities to “try and make that happen”, adding there would be a multi-agency meeting at 13:00 GMT where “everything will be reassessed and reviewed”.

“Plans are being put in place and residents are being spoken to around what that will look like.

“I can’t make any promises in relation to that, but we want to minimise disruption as much as we can,” she added.

Police said a controlled explosion was carried out at about 16:00 on Thursday, with Derby City Council confirming accommodation had been arranged for affected residents for Thursday night “and the coming days”.

The entirety of Vulcan Street was covered by the evacuation zone, as was Reeves Road and Shaftesbury Crescent.

Harrington Street, from Holcombe Street to Vulcan Street; Baseball Drive, up to Columbo Street, and Cambridge Street at Reeves Road and Shaftesbury Crescent were also included within the exclusion area.

Baggy Shanker, MP for Derby South, said the situation had been “very difficult” for the local community, but added he had been told that everyone who needed accommodation had either been supported by friends and family, or had been put in a hotel.

“That just shows the strength of the community spirit here,” he added.

Amjad Ashraf, who runs the Pakistan Community Centre, said about 50 families had come in on Thursday afternoon, and told the BBC many had found alternative accommodation for the night.

“We reassured everyone that if you’ve not got anywhere to stay with friends or family, Derby Homes are on site and they’re going to be putting people in hotels.

“The community in the Normanton area always rally around really quick to provide that support.

“We had the Gurdwara which is also on Harrington Street providing refreshments and some food. We had volunteers that came together to provide that emotional support, a bit of hand holding, and at times like this, that’s what’s mainly needed,” he said.

John Morley, 86, lives in the evacuation zone and stayed overnight with his daughter in Allestree.

He told the BBC he was about to put his feet up for a sleep at about 13:30 when a police officer knocked on his door, telling him he needed to evacuate his home.

“I grabbed my tablets, my coat and umbrella, and that was it,” he said.

“I’m OK, it’s just an experience. To think that was going on on our doorsteps.

“I’m eager (to get back in), because it’s odd when you leave your home.”

Amy Anderson, who lives on Shaftesbury Crescent and is six months pregnant, told the BBC she spent the night at her mum’s house with her son, and said she felt like she was “in limbo”.

“I’m hoping we’ll be able to get back in today, but I left the property thinking we would be able to get in last night, so I don’t really know,” she said.

Ms Anderson added she was “very fortunate” to be able to stay at her mum’s house and she knew some neighbours had been put in hotels for the night.

The two men who have been arrested are Polish nationals, Derbyshire Police has said.

A police spokesperson told the BBC it had released this information in line with national guidance around forces being encouraged to disclose the ethnicity and nationality of suspects to combat misinformation.
