I've sure had Frobay as an ETOPS alternate a few times over the years but I've never had the pleasure of landing there.
Sounds like Speedbird One Yankee Charlie diverted for electrical or airconditioning fumes on the flight deck, shut down on runway 16-34, got checked out by Red One and the rest of the CFR crew. Restarted engines and taxied to the ramp to deplane the pax to the terminal. Speedbird called HQ in LHR to confirm the plan for deplaning. A pax requested medical assistance for arm and chest pain and paramedics were boarded prior to pax deplaning.
