Presidential candidate Elizabeth Warren‘s campaign office in Manchester, New Hampshire was broken into Wednesday night. Other offices in the same building were also vandalized, the campaign said, making them believe Warren was not specifically targeted.

“We have no reason to believe this was targeted to the campaign or is anything further than a regular break in, and we are working with authorities,” Andrew Taverrite, a spokesperson for the campaign, said in a statement.

According to police logs, the break-in at the office was reported at 9:16 a.m. Thursday.

The campaign did not specify what, if anything, was stolen.

Warren’s field office in Manchester is one of five in New Hampshire. It is often viewed as a critical state to campaign in, as it is the first state to hold nationwide primary elections. New Hampshire’s primary elections are also not “closed,” meaning unaffiliated voters can vote in either party’s primary.

The primary in New Hampshire will be held on Feb. 11.

Warren has emerged as a frontrunner for the democratic nomination, polling just below former Vice President Joe Biden. A RealClearPolitics national average of polls shows her trailing Biden 27.2% to 21.8% among voters.
