FREMONT -- A woman that police say was high on bath salts is undergoing a psychiatric evaluation after officers found her standing barefoot in a busy intersection, randomly screaming and unable to give her name.

Officers were called at 10 p.m. Tuesday to Fremont Boulevard at Becerra Drive for a report of a "highly agitated female" standing in the middle of the street, police spokeswoman Geneva Bosques said.

Police found the shoeless 24-year-old woman standing in the center median north of Tamayo Drive. She could not speak or give her name and would occasionally start screaming, Bosques said Thursday.

"After being detained, the woman was restrained to a gurney but would periodically scream for no reason," Bosques said.

About 3:20 a.m. Wednesday, she was finally able to give her name, which was not released. A records check revealed she had done the same thing in May 2012 in the same intersection, Bosques said.

Paramedics took the woman to a medical facility to be evaluated, Bosques said.

"Bath salts and spice are becoming an increasingly difficult problem for law enforcement as they are new and research is still being done on the effects and health risks related to these substances," Bosques said. "Bath salts are believed to be linked to multiple suicides throughout the nation and Fremont Police Department has seen at a couple of cases with people on bath salts who are out of control or highly irrational."

The incident comes about a month after Fremont Police Department officers seized synthetic cannabinoid (Spice), salvia and illegal bath salts from Rocky's Smoke Shop in Crossroads Shopping Center and Monsters of Rock Smoke Shop, in the Irvington area of the city.

The seizure, which police say was not directly related to this week's incident involving the 24-year-old woman on Fremont Boulevard, was on Oct. 23. About two weeks later, Rocky's Smoke Shop owner Vijay Pate, and the manager of Monsters of Rock, David Ghebreab, were arrested on suspicion of selling, dispensing and distributing a synthetic stimulant compound and on suspicious of possession of concentrated cannabis, Bosques said.

Bosques said about six pounds of synthetic cannabinoids and several grams of bath salts were recovered during the bust. Their estimated street value is more than $25,000, she said.

Anyone with information regarding the illegal sales of either of these substances is asked to call Fremont Police Department at 510-790-6800 or send a tip to www.fremontpolice.org/tip.
