A 20-year-old Glendale man was arrested Thursday after police said he struck an elderly woman in the head with a shovel and then barricaded himself inside his apartment. It took a rubber bullet and Taser before officers were finally able to subdue him.

The man, Robert William White, sat handcuffed in a wheelchair yelling “God loves all you!” several times to bystanders as paramedics removed him from his apartment in the 1000 block of Spazier Avenue and transported him to a nearby hospital. He admitted to police that he had been drinking soda spiked with the synthetic drug known as bath salts.

“He seemed completely out of sorts,” said Northwest Glendale Police Lt. Bruce Fox.

White barricaded himself inside his apartment for nearly an hour until police opened his front door using a key and walked inside to get him, Fox said.

Police were initially called to the scene about noon after getting reports that White had attacked a woman in a nearby apartment building.

Witnesses told police that the woman, whose age could not immediately be confirmed, had asked White to stop swinging his shovel at birds before he allegedly used it to strike her in the head.

Neighbor Salbi Dgeredzyan said White told the woman, “I hate you and I want to kill you today.”

The woman, whose name wasn't released, was taken to a nearby hospital, where she was treated for what police described as non-life-threatening injuries.
