  Ram-pressure stripping by the intracluster medium (ICM) is one of the most
advocated mechanisms that affect the properties of cluster galaxies. A recent
study based on a small sample has found that many galaxies showing strong
signatures of ram-pressure stripping also possess an active galactic nucleus
(AGN), suggesting a possible correlation between the two phenomena. This result
has not been confirmed by a subsequent study. Building upon previous findings,
here we combine MUSE observations conducted within the GASP program and a
general survey of the literature to robustly measure the AGN fraction in
cluster's ram pressure stripped galaxies using BPT emission line diagrams.
Considering a sample of 115 ram pressure stripped galaxies with stellar masses
$\geq 10^9 \, M_{\odot}$, we find an AGN fraction of $\sim27\%$. This fraction
strongly depends on stellar mass: it raises to 51% when only ram-pressure
stripped galaxies of masses $M_* \geq 10^{10} \, M_{\odot}$ are considered. We
then investigate whether the AGN incidence is in excess in ram pressure
stripped galaxies compared to non-stripped galaxies, using as comparison a
sample of non-cluster galaxies observed by the survey MaNGA. Considering
mass-matched samples, we find that the incidence of AGN activity is
significantly higher (at a confidence level $>99.95\%$) when ram-pressure
stripping is on act, supporting the hypothesis of an AGN-ram pressure
connection.
