No, even in my very small country with generally pretty tech-impaired police department, this was common before 2010. There was a big issue I think around 2006 because the police requested the list of IMEIs present near a particular rural transmitter to help investigate a murder, their court order was rejected as the transmitter was serving a huge area and it was deemed too large a privacy violation for too many people.

I'm sure it was done many times before that, and I'm also sure we were not the first.
