In the latest development since the targeted attack on a southern California Pacific Gas & Electric Co. substation last April, PG&E is offering a $250,000 reward for information leading to an arrest and conviction in the attack.

According to The Associated Press, the attack left AT&T fiber-optic lines disconnected, knocking out phone and 911 service in the area around Silicon Valley, and the attackers fired shots into the substation, knocking out 17 transformers and causing more than $15 million in damage.

“One year later, the perpetrator or perpetrators of this crime remain at large and we want to help change that,” said Gregg Lemler, PG&E’s vice president of electric transmission operations, at a news conference Thursday.

The reward would be funded by shareholders and comes nearly a year after AT&T offered its own $250,000 reward for information leading to an arrest.
