Castlebar Gardaí recovered a bicycle stolen from the GMIT car park at Mayo University Hospital which belonged to a frontline worker.
The property was taken from the bike shelter in the car park on Thursday while its owner was working in the hospital.
Gardaí obtained a warrant and searched a house in the town on Friday.
A male in his teens was arrested and the bicycle was recovered.
He has since been released and a file is being prepared for the National Juvenile Office and the DPP.
