( KTRS ) Authorities continue to investigate a 12 hour standoff between police and a man that held 2 people hostage.

The standoff began Sunday when a caller told police a man was making meth in the garage. Police reported Monday that the 53-year-old suspect showed a shotgun and refused to leave. That led to a standoff while two victims, ages 22 and 25, were inside the home.

SWAT teams responded and the standoff ended around 11 p.m. Sunday. Neither victim was hurt.

As of midday Monday, formal charges had not been filed. Police say an active meth lab was found.
