Barking and Dagenham

They are now living in temporary accommodation in Barking and Dagenham, about 50 minutes' drive to her children's school.

Det Supt Lewis Basford, who is responsible for policing in Barking and Dagenham, said investigators "believe those involved were known to each other and we are not looking for anyone else in connection with this incident".

His reputation as a skilled campaign strategist was further cemented in Barking and Dagenham, where the far-right, anti-immigrant British National Party was gaining support and hoping to win its first parliamentary seat 2010.

The displaced residents who have not been staying with friends or family have been provided accommodation in hotels paid for by Barking and Dagenham Council.

Barking and Dagenham Council has said the building affected by Monday's fire was privately-owned, but that it was working to provide support to residents.
