Police taped off a back lane on Daly Street South between Rathgar and Walker avenues after a “serious domestic” incident, a spokesperson told CTV News.
Police received reports of shots fired.
"Several units attended to the area, and shortly thereafter a male was located and taken into custody," said Const. Eric Hofley.
A garage appeared heavily damaged, and police markers covered part of the ground in the back lane.
The investigation is ongoing.
