Over 1,800 official complaints were made against Gardaí to their watchdog last year.
Provisional figures show the Garda Síochána Ombudsman Commission received 1,826 complaints last year, which is 17% lower than in 2021.
According to freedom of information figures, there were 14 allegations of sexual offences by Gardaí.
Last year's complaints contained just under 3,000 allegations. A third of them were in Dublin, with 266 in Cork and 119 in Mayo.
But the vast majority of last year's complaints weren't upheld, with only 12 breaches of discipline identified so far.
Damien McCarthy, from the Garda Representative Association, says many of the complaints were false or malicious, "The figures speak for themselves".
"It goes to show that the constant narrative that has been portrayed in the media over the last number of months and years in relation to corruption and wrongdoing in the guards simply is not true.
"I think if you look at the GSOC figures, the number of complaints that are going into GSOC, the vast majority of those complaints are not being upheld".
Of all the allegations nationally, 33 were about theft and fraud, and 15 were related to discrimination.
