Around 120 residents who were evacuated from their homes in north London shortly after midnight because of a gas leak have returned home.
Residents were cared for by the local authority while the leak, which was caused by road maintenance work in the area, was attended to in Enfield.
Police, London Ambulance Service and London Fire Brigade were at the scene along with National Grid engineers.
The leak has been fixed and residents have now returned to their homes, while local train services have also resumed.
Dozens of confidential social services files, including notes on the Victoria Climbie case, have been found at an old town hall which is being used as a set for a TV drama, an MP has said.
An "urgent investigation" has been launched by Enfield Council in north London after the documents were left on public view on shelves and tables at the former civic centre in Southgate, the set for the police station in the new Inspector Morse drama series.
Tory MP David Burrowes, who discovered the files while campaigning, said he was shocked at the council's negligence.
"It is an abuse of information and negligence and it's completely unacceptable," he said.
The files also contained details of parents turned down for adoption, the phone numbers and addresses of vulnerable people on the service's register, and financial information.
A council spokeswoman said: "Now that this matter has been brought to our attention we are conducting an urgent investigation to establish the facts."
