Model Description

When a BH evaporates to some critical mass, a fireball of e+− pairs can be created. The relativistic pairs expand into the magnetic field of the surrounding ISM, which, for a sufficiently low mass BH, could produce a emission consistent with an FRB.

Observational Constraints

In this scenario the inferred distance to the Lorimer burst is calculated to be 200 kpc -- far too low, thus making this theory inviable.
