Burglars stole 30 tablet computers and one laptop “containing sensitive campaign data” from the Buena Park campaign headquarters of GOP Assemblywoman Young Kim early Sunday, according to representatives from Kim’s camp.

Police on Monday confirmed electronic office equipment was reported stolen from the office at 6940 Beach Blvd., but did not specify how much. Police said “there is no suspect information available.”

Kim’s campaign speculated the break-in might be politically motivated. But her opponent in the race for California Assembly District 65, Democratic former-Assemblywoman Sharon Quirk-Silva, denied that her campaign had any connection to the burglary and offered to contribute toward a reward to help find the culprit.

Kim’s campaign said the break-in occurred between the time staffers left headquarters on Saturday night and when they returned on Sunday.

Kim and Quirk-Silva are running a hotly-contested race for a seat that could determine the balance of power in the statehouse by granting or denying Democrats a supermajority that would allow them to pass tax increases without any support from Republican lawmakers.

Those stakes have made the race one of the most expensive in the state, with over $2.6 million in expenditures backing Kim and $3.6 million supporting Quirk-Silva.

On Monday, Kim’s campaign consultant Dave Gilliard said he suspected a political motivation because her campaign headquarters are on the fourth floor of a mostly unoccupied building and the office has no internal windows to view its contents. He said the stolen computers contained data about the district’s voters, including research about what issues are important to them.

“Whoever did this knew exactly what they were doing, and to whom,” Gilliard said.

Qurik-Silva released a statement on Monday, saying she had called Kim and offered to contribute to a reward to help catch the burglar.

“Whoever did this must be caught and punished to the fullest extent of the law,” said Quirk-Silva, who held the Assembly District 65 seat from 2012 to 2014, when she lost it to Kim. “I can say without hesitation that no one from my campaign would ever participate in such an awful act.”

Gilliard said the Kim campaign was unlikely to offer any such reward.
