Residents react to explosion
Two neighbouring properties partially collapsed and eight others, as well as 20 cars, were damaged by debris, the force said.
About 50 people from 35 properties were evacuated and were being supported by Bassetlaw District Council and Nottinghamshire County Council.
Some of the displaced spent Saturday night in the Crown Place Community Centre, which was offered as an emergency shelter.
Nottinghamshire Fire and Rescue Service reported the incident as a suspected gas explosion, while police said they were continuing to investigate the cause of the blast.
