HAYWARD -- Service of an eviction notice at a Hayward home Tuesday morning turned into an all-day ordeal involving a SWAT team, bomb squad technicians and search robots after deputies found threatening notes inside the residence and called for backup, authorities said.
No one was home at the time and no one was injured, said Alameda County Sheriff's Office spokesman Sgt. Ray Kelly.
The search of the house in the 27000 block of Gainesville Avenue began about 10 a.m. Tuesday when Alameda County Sheriff's deputies attempted to serve an eviction notice.
Deputies went into the home and found a note on a wall that warned of explosives in the house. The note also said the house was rigged to blow up. Deputies cleared out and called the Hayward police SWAT team and the sheriff's office bomb squad for assistance. Bomb dogs and robots were used to make sure the house was safe, Kelly said. A spent bullet casing was found but nothing else, Kelly said. Police cleared the scene about 6 p.m.
No arrests were made but the case remains under investigation.
