Middletown Police are not yet using BRIC's, so I'm not sure what radio ID's you could be referring to in use by Middletown PD.
Middletown Fire is multicasting dispatch on their main BRICS talkgroup and 154.250, but that is FD not PD. MPD is still utilizing their VHF repeaters on 155.730 and 155.430 at this time.
