In the Letter, interesting evidence is reported to support a central tidal
disruption event (TDE) in the known AGN NGC 1097. Considering the motivations
of TDE as one probable origination of emission materials of double-peaked broad
emission lines and also as one probable explanation to changing-look AGN, it is
interesting to check whether are there clues to support a TDE in NGC 1097, not
only a changing-look AGN but also an AGN with double-peaked broad emission
lines. Under the assumption that the onset of broad H emission was due
to a TDE, the 13years-long (1991-2004) variability of double-peaked broad
H line flux in NGC 1097 can be well predicted by theoretical TDE model,
with a main-sequence star tidally disrupted by the
central BH with TDE model determined mass about .
The results provide interesting evidence to not only support TDE-related origin
of double-peaked broad line emission materials but also support TDE as an
accepted physical explanation to physical properties of changing-look AGN.
