Almost 1000 incidents of anti social behaviour and threats to passengers and staff happened on the LUAS last year.
LUAS operators Transdev said the majority of incidents happened on the red line.
Last year there were 677 public order offences on the LUAS and a number of prosecutions are currently with gardai.
Staff and passengers were also subjected to abusive behaviour on 199 occasions.
However there was no figure for how many thefts took place in 2013.
Despite the figures LUAS operators Transdev said that the Red and Green Lines were safe and reliable.
Transdev held meeting with gardai every 2 months last year and says it will continue to work with authorities to combat crime.
The company also uses its own security measures which consists of seven 2 man guard teams to patrol the red line during business hours.
