Gardaí on an Operation Fanacht patrol to enforce the lockdown discovered cash and drugs when they stopped a man.
The seizure came in Co Clare and the 26-year-old man stopped is understood to be known to gardaí.
He was spotted by officers on a housing estate in Newmarket-on-Fergus at around 3pm on Saturday.
Gardaí recognised the man as not being from the area and being considerably more than 2km away from his home.
They stopped him and after speaking with him for a time, their suspicions were further aroused so they decided to carry out a search under the provisions of the Misuse of Drugs act.
During the course of the search, gardaí discovered more than €2,000 in cash as well a quantity of drugs comprising cocaine, cannabis and Xanax tablets with an estimated value of €700.
It is believed the man was making deliveries to local customers in their homes when he was stopped. The cash and drugs were seized while the drugs will also be sent for analysis.
The man was not arrested, however the Garda investigation into the matter is continuing.
Also in Clare on Saturday, gardaí seized a rifle, an imitation handgun, and a small amount of drugs as well as several electronic devices.
Members had been carrying out a Covid-19 patrol in the Kilmihil area when they observed a man in possession of a rifle.
After speaking to the man and making further inquiries, it transpired the male, in his late teens, did not hold a firearm licence.
