The ATCO is out of order. To "pursue" an individual via an MOR is not what the CAA are interested in; it's not what the system is there for. Let him report it but don't worry about it, as already stated above.
I had someone do this to myself. I was named in an MOR as the pilot causing damage to an airfield installation with rotor downwash, failing to comply with airfield procedures and causing an airprox. The CAA reply was as above.
I wasn't on duty at the time of the alleged incident, btw, but I was given a copy of the paperwork and the follow up report.
