The mysterious metal cylinder was capped at one end and had a pin attached to its side. Bomb experts from Walnut Creek evacuated everybody for 300 feet around and blew it up at about 10:30 pm.
It turns out it was a pipe, but not a pipe bomb. Police now think it was a marijuana bong left behind by some taggers who were seen vandalizing the house and a car at about 6 pm.
