GARDAÍ believe a dispute between members of an extended family led to shots being fired at a house in Knocknaheeny.
A number of shots were fired at a property on Ardmore Avenue at around 10.40pm on Thursday night.
However, it is understood the shots were blanks and no damage was caused to property, and nobody was injured.
Gardaí believe the shooting served as a warning to the occupants of the house.
No complaint has been received in relation to the incident.
There were also reports of a petrol bomb being thrown at the same house a number of hours before the shots were fired. However, no complaint was received by gardaí in relation to that either.
The armed response unit attended the scene.
Meanwhile, two men were in custody last night after staff and customers of a shop in Grenagh foiled an attempted raid yesterday morning.
Costcutters in the village was targeted at 8.30am when one man went into the shop and tried to take cash. People in the shop at the time managed to apprehend him and gardaí were called. He was arrested at the scene.
In the meantime, a second man fled from the store in a car which a garda spokesman said is believed to have been stolen.
The spokesman said the vehicle was involved in a single-vehicle collision a short time later and the driver was also arrested.
One of the men is in his late teens while the second is in his early 20s.
