An enhanced giant pulse generated by a rapidly spun-up neutron star near a spinning black hole could produce a single FRB. A gyroscope is used to model the pulsar's spin-precession, which has been shown to increase rapidly near the event horizon of a Kerr BH. Eventually the spin precession exceeds the pulsar's spin, and the latter can be neglected. As such, the pulsar magnetosphere is essentially rotating around the spin-precession axis. The rapid spin-up causes a giant pulse, whose emission is consistent with an FRB.
If two or more bursts are released during the rapid spin-up, the event duration is expected to be >1 ms for an unresolved burst and a double peaked profile is expected if the burst is partially resolved.
