A man was arrested near the Republican National Convention in Milwaukee after an AK-47 pistol was found in his backpack, according to local and federal officials. His intentions, if any, were not immediately clear.

The incident happened at around 1 p.m. on Monday when U.S. Capitol Police observed a suspicious person with a ski mask and a large tactical backpack in the 1200 block of N. 11th Street, just a few blocks from the convention.

“Capitol Police performed a subject stop and it was determined that the suspect was concealing a firearm in his backpack,” police said in a statement on Tuesday. “The suspect does not have a legal CCW [Concealed Carry Weapon] permit in Wisconsin or any other state.”

Federal law enforcement sources told CBS News and Fox News that the backpack contained an AK-47 pistol, a full magazine and a ‘Scream’ mask. His intentions, if any, were not immediately known.

Milwaukee Police said charges are pending a review by the Milwaukee County District Attorney’s Office.

Security at the convention is high after the attempted assassination of former President Donald Trump at a campaign rally in Pennsylvania on Saturday. Trump was shot in the ear, one person in the audience was killed and two more were injured.

A man armed with an AK-47 pistol and wearing a ski mask was arrested on Monday just blocks from Fiserv Forum where the Republican National Convention is being held in Milwaukee, a federal law enforcement source confirmed to Fox News.

Inside the bag, police found the gun and a full magazine. His intentions were unclear.

Milwaukee Police confirmed the incident to Fox News, saying a 21-year-old man was arrested around 1 p.m. on Monday on the 1200 block of N. 11th Street.
