21-year-old man was arrested near the Republican National Convention in Milwaukee, Wisconsin, on Monday, while wearing a ski mask and carrying an AK-47 pistol with a full magazine in a tactical bag.

Homeland Security Investigators and Capitol Police were conducting surveillance near the RNC perimeter when they noticed a suspicious man approaching, according to a Fox News source. The man was wearing a ski mask and carrying a tactical bag.

Upon inspection, police found a gun and a fully loaded magazine inside the bag. The man's intentions were unclear.

Milwaukee Police confirmed to Fox News that a 21-year-old man was arrested around 1 p.m. on Monday on the 1200 block of N. 11th Street. They stated that the man does not possess a concealed weapon license in Wisconsin or any other state. Charges are pending review by the Milwaukee County District Attorney's Office.

Fox News reached out to the Secret Service regarding the incident but was referred to Milwaukee Police. Inquiries to Homeland Security Investigations and the Department of Homeland Security have not yet been answered.

This incident is not the only security concern at the RNC. On Tuesday, a man was shot and killed by police approximately 2 miles from Fiserv Forum. A witness told Fox News the man, who lived in a nearby homeless camp, was brandishing a knife when he was shot.

Additionally, on Tuesday, Rep. Derrick Van Orden, R-Minn., reported being assaulted by a protester while waiting in line to enter the venue. He described the encounter as an "incident of political violence." CODEPINK, the activist group involved, claimed the woman "was intentionally bumped into by this bald, white member of Congress while he tried to shove past her," denying that Van Orden was assaulted.
