Two homemade bombs were found Friday morning at Inspiration Point in Berkeley’s Tilden Regional Park, but officials said they were amateurishly made and therefore not hazardous.

The bombs were found at 11:36 a.m. by an East Bay Regional Park District staff member. As soon as it was determined that the bombs were potentially dangerous, hazardous materials specialists from Contra Costa County were called, said Jon King, a lieutenant of the East Bay Regional Park Police Department. The bombs were thought to be “pool acid” bombs because they were plastic bottles filled with chemicals.

The police were greeted by a false alarm, however, as the bombs turned out to be filled with ammonia rather than “pool acid” and did not detonate.

“It was probably made by kids who thought they knew what they were doing,” said Charles Nicholson, a Contra Costa County hazardous materials specialist. “As far as we know, there is no threat.”

The specialists reported to the scene along with the Walnut Creek Police Department within 45 minutes, Nicholson said.

Upon arrival, the immediate area was cleared, King said. Though he said he did not know how many people were present, he said the park had been open since 5 a.m. and Inspiration Point is generally a “fairly populated area.”

If the bomb had been assembled correctly, it probably would have splashed anyone within an eight- to 20-foot radius with acid, Nicholson said.

Nicholson added that acid bombs take “zero experience” to assemble, made up of hydrochloric acid, aluminum and a plastic bottle. However, both he and King said finding the bombs is not a common occurrence.

King said he could not remember the last bomb found, though he said it was not within the past year. Contra Costa County hazardous materials specialists get bomb-related calls “about once a year,” Nicholson said, though this is the first he could recall one from Tilden.

Park visitors also did not seem disturbed by the incident. Four people who had read about the bomb Monday morning still came to Inspiration Point that day. Other visitors seemed similarly unconcerned.

Karen Ford, an El Cerrito resident who said she grew up playing in Tilden, said although she may be more cautious bringing her children to the park now, the incident would otherwise not deter from coming.

“People say they have sighted mountain lions in the park, and that doesn’t stop me,” she said.

Erica Smith, a Crockett resident planning to move to Berkeley soon, said the incident will not discourage her from coming to the park or to Berkeley.

“It seems like a really safe area, really community oriented,” Smith said. “I don’t actually know about (the bomb incident), but I would guess it is just a fluke.”
