There will be a special sitting of the Letterkenny District Court tonight (Sunday) to hear cases from the rally weekend.
Gardaí dealt with a high number of arrests in the past three days following various incidents in and around Letterkenny.
Forty-one people were arrested on a busy Saturday night and sixteen arrests were carried out on Friday. Offences included public order, misuse of drugs, dangerous driving, drink driving, assault and the assault of a Garda member.
A small number of those cases are expected to come before the special court sitting tonight.
