US Capitol Police arrested a Virginia man as he attempted to pass through a police checkpoint in downtown Washington, DC, Friday with fake inaugural credentials, a loaded handgun and more than 500 rounds of ammunition, according to a police report and a law enforcement source briefed on the situation.

The incident occurred shortly after 6:30 p.m. when Wesley Allen Beeler pulled his pick-up truck to a police vehicle checkpoint at North Capitol and E Street NE, just north of the Capitol building, the source told CNN.

Beeler, from Front Royal, Virginia, presented officers with what was described as an unauthorized inauguration credential.
