The number of complaints of anti-social behaviour on the Luas has increased by a third over the last three years.
There were 787 reports last year, up from 702 in 2020 and 593 in 2019 according to freedom of information figures.
That's despite the number of passenger journeys falling by more than half to around 19 million during 2020 and 2021, compared with over 48 million journeys in 2019 before the pandemic hit.
While complaints of vandalism increased by almost 7 per cent last year to 778. That included vandalism to trams but also the entire Luas network and included etching or scratching on glass and graffiti.
Dublin bus
Meanwhile, complaints on anti-social behaviour on Dublin Bus have fallen from 185 in 2020 to 130 last year.
A spokesperson for the travel company says it operates a fleet of 1,000 buses and that "while the operation on such a large scale is challenging, the level of anti-social behaviour is relatively low."
They went on to say overall incidents of anti-social behaviour and vandalism on buses have decreased in recent years since the introduction of the exact fare system, CCTV and security screens at the driver's cab.
The Dublin Bus fleet is also fitted with CCTV cameras, with up to ten internal cameras and two external cameras fitted on the more modern vehicles.
