WOODSTOCK, N.B. -- A 35-year-old man from New Brunswick's Woodstock First Nation now faces seven charges following an armed standoff.

The Mounties responded just after 3 p.m. Sunday to a report that an intoxicated man with a loaded rifle had been uttering threats on Eagles Nest Drive on the reserve.

Officers say the man had barricaded himself inside a home and surrounding homes were evacuated.

A negotiator was brought in and the man surrendered to police shortly after 2 a.m. Monday.

The RCMP initially said there was an exchange of gunfire between officers and the man, but they later said it's unclear whether he fired his weapon at them.

Chad Tomah was charged Monday with carrying a weapon dangerous to the public peace.

On Thursday, other charges including assaulting a police officer, pointing a firearm, recklessly discharging a firearm and careless use of a firearm were added.

He is to undergo a psychiatric assessment before returning to provincial court on Feb. 12.
