All three incidents occurred yesterday, and are separate from each other.
Investigations are underway in Laois after a "theft rampage," an assault on a member of Gardaí, and a large sum of cash was stolen.
In two of the incidents, which are separate from each other, court appearances are due today.
A man in his 40s is due in court today after assaulting a female Garda at the National Ploughing Championships in Ratheniska at around 4.30pm yesterday.
She suffered head and facial injuries in the incident, but Gardaí say she's doing well now.
The man involved will appear before a sitting of Portlaoise District Court this afternoon.
In another incident at the Ploughing, a large sum of cash was stolen from a car between 3-5pm yesterday afternoon, after one of the windows was smashed.
Anyone with any information in relation to that is being asked to contact Portlaoise Garda Station.
A woman in her 30s is also due before Portlaoise District Court today, following a string of thefts from shops in the town yesterday.
