WESTON - Police say a pair of copper thieves triggered an oil spill in Weston today.

Investigators say 37-year-old Jose Morales and his brother, 42-year-old Mauro Morales, stole copper piping from a home at 153 Valley Forge Road, inadvertently contaminating the Saugatuck River after they accidentally severed an oil line.

The Saugatuck River is known for its trout population, which experts say is among the healthiest in the country.

The Town of Weston has hired contractors to clean up the oil, and authorities say the spill is still under investigation.

Police say both men are free on bond and will be back in court in January.
