The officer’s wife and several children were inside at the time, but no one was hurt.
RCMP had ordered Clyde River’s 1,000 residents into a lockdown on Thursday morning after warning there was an active shooter in the community.
Police say they had earlier responded to a call of an alleged assault and an intoxicated suspect, then went to the home of the RCMP detachment commander.
They say two rifle rounds were fired through a front window.
A man was arrested and is to be charged with several offences that include uttering threats, assault with a weapon and firearms charges.
RCMP say the victim of the assault is expected to make a full recovery.
“The involved RCMP members and families have all been provided available support to ensure their personal health and wellness,” a release said Friday.
“Appropriate contingencies were put in place to ensure that there was no interruption to the provision of policing services to the community.”
