Police have brought a felony gun charge against a member of a prominent Chicago family who was arrested after he approached security barriers outside Barack Obama's home.

The family of 31-year-old Omhari Sengstacke released a statement saying he had no intent to harm the Democratic presidential candidate or his family. The U.S. Secret Service also has insisted he never posed a threat to Obama.

Sengstacke was apparently intoxicated but not armed when he was arrested about 6:30 a.m. Tuesday. The gun was found in his car.

Omhari Sengstacke is the grandson of John Sengstacke, longtime publisher of the Chicago Defender.

The newspaper waged a prominent campaign against segregation, sparking blacks' migration to Northern cities.
