According to BBC News website, Greater Manchester Police have set up a 24-hour Twitter feed so every call it receives can be made public.

More details:

The feed has revealed the extremely varied nature of emergency calls the force receives.

One minute someone is calling about a baby being dangled over a bridge - although later it turns out that it was a dog.

Shortly afterwards, the force receives another 999 call about fireworks being set off in a local park.

Then another call is received about a missing mother and son, and at the same time another operator is taking down details of a missing person who has been found.

Another tweet from a member of the public congratulates the police on the finding the missing woman, then a second later there's a robbery in Salford to attend to.
