Officers from Derbyshire police have said the non-emergency phone line number 101 has now returned to normal after four days of problems.
Staff in the contact management centre were evacuated on Monday, December 18, due to a water leak at the force's headquarters at Butterley Hall in Ripley. They moved to another office.
Officers said that people trying to contact the non-emergency number might have experienced delays on Monday and were urged to use the force's website to report incidents to the police instead.
People call 101 for non-emergency situations, such as reporting minor criminal damage, livestock having escaped and for passing on information on crimes the police have issued an appeal on.
Superintendent Simon Tunnicliffe said: "If anyone has experience delays during recent days, I'd like to apologise for the inconvenience and thank people for their patience.
"Moving to back-up accommodation is something we prepare and practice for.
"It came to fruition here and we are pleased that disruption to the service we provided was kept to a minimum."
The force is still urging members of the public to try other ways to get in touch with officers.
- Only call 101 if you need to. Anyone calling about a police matter can get in touch with officers on the Contact Us page on the website.
- The website www.askthe.police.uk can be used to ask questions about a range of policing matters.
- If the query does not need addressing now, you can use the Request a Call Back on the website to be called back by a member of the call centre team.
- In an emergency, call 999. This number is not affected.
