SAN ANTONIO (Reuters) - Three foreign nationals in their twenties are being questioned by authorities after they were arrested inside the Bexar County Courthouse in downtown San Antonio early on Wednesday, law enforcement officials said.
"They are going to be held for interrogation by the FBI, Immigration and Customs Enforcement, and the joint terrorism task force," San Antonio Police Captain Cris Anderson said.
Officials said two of the men crawled through a window around 2 a.m. to get into the 120-year-old courthouse, a landmark in downtown San Antonio, and the third was found in a van parked in front of the building.
Officials immediately blocked off a two-square-block area of downtown San Antonio around the Courthouse, and bomb sniffing dogs fanned out throughout the building.
About two hours later, the streets were reopened, indicating nothing dangerous was found in the building.
Inside the van, officials say they found "photographs of infrastructure" including photos of shopping malls, water systems, courthouses and other public buildings which they say were taken in cities nationwide.
"They got travel documents, parking passes, they have been all over the country," Anderson said.
"A lot of photographic equipment, a lot of documentation equipment inside their vehicle."
