A cache of weapons that included an illegal assault weapon was found during a routine probation compliance search at a residence in Glendora, officials said Thursday.

The search was conducted on Wednesday at the residence of a man on probation, according to Adam Wolfson of the County of Los Angeles Probation Department.

“The probationer and his brother, the alleged owner of the illegal assault rifle, subsequently were arrested by the Glendora Police Department,” Wolfson said. Their names were not immediately made known.

The discovery of the contraband, which included handguns and an AK-47 assault weapon, was made with assistance from a police dog named Penny, who alerted on ammunition boxes in the living room of the residence and on firearms in a bedroom.

“The dogs and the handlers that make up the Canine Detection Team have become an effective tool for L.A. County Probation,” Probation Chief Deputy Reaver Bingham said.
