Gardaí are appealing for witnesses and potential victims following a number of reported assaults that occurred in the Connolly Station area on Wednesday.
Gardaí received a number of reports of assaults on females in the area on Wednesday morning.
A man was arrested at the Museum Luas stop later that day.
The man, a non-Irish national aged in his 50s, was detained at Store Street Garda Station.
