I guess the police can use the MAC address to identify the laptop on recovering it, making sure of the ownership - which is probably why they asked for it. Tracking down a laptop using a MAC address does not seem practically possible for the police or anyone... it is very easy to change the MAC address temporarily while connecting to the internet, and marginally more difficult to change it permanently.
