CUPERTINO — A mountain lion attacked a child alongside a hiking trail near a Cupertino winery on Sunday afternoon, the Santa Clara County sheriff’s department reported.

The 6-year-old boy, who is expected to survive, was attacked around 1 p.m. on a hiking trail along Montebello Road, near the Picchetti Winery.

California Department of Fish and Game officials reported that the boy, who was accompanied by his parents, was apparently dragged into some bushes before being pulled free. The boy was transported to the Valley Medical Center for treatment of “non-life-threatening injuries.”

Sheriff’s department officials reported that they closed off the hiking trail to search for the mountain lion. The state Department of Fish and Wildlife was later put in charge of tracking the animal and determining what steps to take if the big cat is captured.

Spokesman Sgt. Kurtis Stenderup said the circumstances of the attack remain unclear, other than the fact the boy was hiking with other family members about two miles from the winery grounds.

While investigators say the area is known to be an occasional haven for mountain lions, there have not been reports of any attacks or confrontations in recent years.

The winery’s website indicates it leases its property from the MidPeninsula Open Space district.
