A man was arrested trying to break into a Trump campaign office in San Antonio early Wednesday morning. Thirty-eight-year-old Rudy Medina was stopped by an off-duty police officer working as a security guard while he was trying to use a credit card to get into the Trump campaign office.

A local report from CBS Austin explains how the off-duty officer described the incident that led to Medina’s arrest:

According to the officer, he spotted a man waiting for an elevator on the third floor of the building; the same floor where Trump’s call center is located. The suspect, later identified as Rudy Medina, 38, was allegedly holding a bag of tablets and was using a credit card to get into an office. That’s when the officer ordered Medina to get down on the floor.

Sources familiar with the campaign office in San Antonio tell Breitbart News that Wednesday’s attempted break-in is the second incident involving this campaign office. The Trump campaign increased security with around-the-clock security after the unlisted technology office and national call center was broken into and vandalized several weeks ago.

Medina has been charged with two counts of burglary and possession of a criminal instrument. According to the CBS Austin report, the San Antonio Police Department said that Medina has a history of breaking into buildings and they don’t believe he targeted the office for political reasons.
